τοπ goes from the side 11 opposite the base of the stand 15 go off. A side profile 18 • (Figure 2) is at the upper ends of the uprights 17 in supported in the same way as the side profile 16 by the uprights 15 in FIG.

A carriage 19 is on guides 20 (Figure 2) in the base 11 of the frame 10 for longitudinal movement along the Frame 10 stored. The carriage 19 w * has two upper rollers 21 and 22, at a horizontal distance from each other, which are rotatably mounted thereon. The sled also has two lower rollers 23 and 24, which are horizontally spaced further apart than the rollers 21 and 22 are horizontally rotatably mounted thereon away from each other.

An elongated flexible band or strap 25 is attached at one end to the top of the smelt plate 12 and the other end connected to the head of the faceplate. The flexible tape or strap 25 can be made of any suitable material, for example Leather, fabric, wire mesh or thin stainless steel, for example, can be formed.

109849/0269

The belt 25, which is longer than the frame 10, runs over the upper rollers 21 and 22 and under the lower rollers 25 and 24 and forms a loop 26 on the carriage 19. The upper rollers 21 and 22 are arranged at a smaller distance from one another than the lower rollers 23 and 24-, a narrow constriction 27 in the loop 26 between the upper rollers 21 %

and 22 while a wide base is provided between the lower rollers 23 and 24.

The carriage 19 carries a pair of sections 29 and the constriction, whereby the narrow constriction 27 occurs a small transverse gap 31 (Figure 3) is reduced.

Each of the neck portions 29 and 30 is tapered (Figure 1) and acts with curved parts of the flexible

Belt 25, which runs over the upper rollers 21 and 22, m

together.

The carriage 19 has a cutting blade 35 (see FIGS. 2 and 3) that extends through the gap 31 and is movable is stored on it. The cutting blade 35 is arranged so that it is transverse relative to the carriage 19 by the Gap 31 moves.

109849/0269

The cutting blade 55 runs between an upper slide 36 and a lower slide 37 (see Figure 2). The upper carriage 36 is slidably mounted on a pair of parallel shafts 58 and 39 (see Figure 1), the runs transversely to the frame 10 above the top of the belt 25. The lower slide 57 is slidable a pair of parallel shafts 40 and 41 which run transversely to the frame 10 below the part of the belt 25, on which the material 42 is stored for the cutting process.

The SchneidbTait 35 is not shown by a Hechanismus in the sliding guides 36 and 57 guided back and forth. The cutting blade 35 can be circular in cross section and have small, not-shown notches over it have its circumference for cutting in any direction.

A worm 45 (see FIG. 2) is guided with its thread in the upper sliding guide 56 and a worm is received in the lower slide 57 in a similar manner. The worm 45 is connected to it by a reversible motor 45 set in rotation.

109849/0269

A vertical shaft 46 is connected to the upper worm 43 by a spiral gear 47 "and with the lower worm 44 connected by a spiral gear 48. The engine 45 thus drives the worms 43 and 44 in one direction or the other. Thus, the slide guides 36 move and 37 together, one above the other, in one or the other 'direction across the carriage 19.

The longitudinal movement of the carriage 19 on the frame 10 relative to the belt 25 is brought about by a motor 50 (FIG. 2), which is mounted on a support arm 51 (FIG. 1) of the slide 19. The motor 50 puts a shaft 52 in Rotation that is rotatable in support arms 53 (in FIG one, both are shown in FIG. 3) is mounted on the slide 19 with the interposition of a Gear wheel 54 on the motor shaft and a gear wheel 55 on shaft 57.

The shaft 52 has gears 56 and 57 (Figure 2), which are hereby mounted for rotation at both ends. The gear wheel 56 meshes with a rack 58, which is connected to the bottom of the side profile 16. The gear 57 comes with a rack 59, which is on The bottom of the side profile 18 is fastened.

If the motor 50 is thus excited, a longitudinal movement of the slide 19 occurs. The direction of movement of the carriage 19 depends on the direction of rotation of the motor 50.

The cutting blade 35 can thus the most varied of desired shapes in the material 42, daa on the flexible Band 25 is stored, cut. The cutting blade 35 is moved along the carriage 19 when the motor 50 rotates while the cutting blade 35 is moved across the gap when the slide guides 36 and 37 are actuated of the motor 45 are moved. There is thus a universal movement of the cutting blade 31 relative to material 42.

The flexible tape 25, which is used as a table top on which the material being carried during the cutting process is supported by a plurality of rollers 60. As shown in Figure 2, each of the rollers 60 is rotatably mounted on its shaft 61. One end of the shaft 61 is rotatably held in a roller bearing 62, while its other end is rotatably in a roller bearing 63.

109849/0269

The roller bearing 62 runs in a longitudinal slot in a rail 64 which is fastened to the top of the side profile 16 is. The roller bearing 63 runs in a longitudinal slot in a rail 6b, which is connected to the top of the Side channel 18 is connected.

Two groups 66 and 67 of rollers 60 are provided. The first group 66 of rollers 60 has rod members 68, which connect each end of each of the rollers 61 together as shown in FIG.

The group 66 is with the roller 60, which the carriage on is farthest adjacent, via the linkage members 68 with the upright posts 69 on the carriage 19 tied together. The first group 66 of the rollers is thus firmly connected to one side of the carriage 19.

The second group 67 of the rollers is connected to the shafts 61 of each of the rollers 60 together by the linkage 70 firmly connected. The group 67 is with the roller 69 most adjacent to the carriage 19 by the Linkage 70 with the upright posts 71 on the slide 19 on the other side of the slide 19 w. \ e the posts 69 attached. Thus, group 67 is the

1098A9 / 02bb

Rollers attached to the carriage 19 on the other side as the connector of the group 66 of rollers.

As shown in FIG. 1, the two groups 66 and 67 of the rollers connected by their connections to the Carriages 19 are removed, with their end members 68 and 70 with each other via resilient means, for example Springs 72 connected. As can be seen in FIG. 2, one of the springs 72 is behind each end of the rollers 60 arranged and connects the rods 68 and 70 together. The spring 72 provides the desired tension to ensure that the groups 66 and 67 come together be moved.

The roles. 60 going through rails 64 and 65 to each Worn moment, serve to store the tape 25. As Figure 1 shows, the top surfaces of the upper rollers 21 and 22 and the working rollers 60 are arranged substantially in the same horizontal plane.

Since the length of each of the groups 66 and 67 of the rolls must be sufficient to cover substantially the entire length of the belt 25 to carry when the sledge takes you in one of its

109849/0269

ner end positions of its longitudinal movement is the Length of each of the groups 66 and 67 of the rollers selected so that the rollers 60, which do not carry the belt 25, must be stored. Accordingly, a guide 73 is attached to one end of each of the side profiles 16 and 18 " and a guide 74 is fixed against the other ends of the side profiles 16 and 18. The guide 73 works with the group 66 of rollers, while the guide 74 cooperates with the roller group 67.

Each of the guides 73 and 74 has an upper curved one Part 75, which for a smooth transition from the horizontal slots of the rails 64 and 65 to a vertical part 76 of the guides 73 and 74 provides. Each of the guides 73 and 74 has a lower curved one Part 77 which smoothly redirects the direction of the rollers 60 from the vertical to the horizontal.

A lower guide 78 is supported by the face plates 12 and 14 and extends therebetween. The lower one Guide 78 has a curved portion 79 which cooperates on the face plates 12 at one end is attached to the lower curved part 77 of the guide 73, whereby the rollers 60 of the group 66 from the

109849/02 6 3

-H-

vertical part 76 of the guide 73 in a horizontal 'feil 80 of the lower guide 78 are guided.

The guide 78 ″ has a curved portion 81, the the end plate H is attached to the other end. The curved part-81 works with the lower curved part 77 of the guide 74 for guiding the rollers 60 of the group 67 from the vertical part 76 of the guide 74 to the horizontal. Part 80 of the lower guide 78 together.

As shown in Figure 1, the rollers 60 are direct worn on guides 73, 74 and 78. The ball bearings 62 and 63 of the shafts 61 therefore do not carry the rollers 60 on the guides 73, 74 and 78. The ball bearings 62 and 63 only carry the rollers when the lugs 60 are there are to wear the tape 25.

Let us now consider the mode of operation of a material cutting device, which uses the support structure according to the invention, so are due to the longitudinal movement of the carriage 19 to the left (FIG. 1) more rollers 60 of the group 67 in working grip with the belt 25 drawn by supporting their roller bearings 62 and 63 on rails 64 and 65 and the same number

109849/0269

1760A96

of roles 60 of the group 66 from. Working engagement with the Band 25 can be solved by their bearings 62 and 63 from Brackets can be removed by rails 64 and 65. The springs 72 ensure that the rollers 60 of the group 66 follow the movement of the lobes 60 of the group 67, while the rollers 60 of the group 67 are pulled up to be carried on the rails 64 and 65 to become.

If the carriage 19 is moved to the right (FIG. 1) by rotating the Iiotor 50 in the opposite direction is displaced, more rollers 60 of group 66 are drawn onto rails 64 and 65 in a similar manner and provide storage for the belt 25. Equilateral: becomes the same number of rolls 60 of group 67 is removed from the carrier by rails 64 and 65. As previously mentioned, the springs 72 ensure da3 the rollers 60 of the second group in the same number from the carrier through the rails 64 and 65 removed as the rollers 60 of the group 66 on the rails b4 and 65 to be carried by them, be moved.

Jas cutting blade 35 was previously considered circular and with
