The angularly adjustable middle batten has one of its ends below the weaving plane of the loom and its other end displaced from the weaving plane.

5 Claims, '7 Drawing Figures PATENTED AUG 2 6 I975 SHEET 2 BF 5 PATEmEmuszsms 3, 901 290 sum 3 BF 5 TEMPLE The present invention relates to a temple for holding or laterally tensioning fabrics in looms.

Most of the materials woven in looms must be tensioned during weaving or held for preventing lateral shrinking thereof. For that purpose, various types of temples are used, according to the properties of the woven material.

Beside little used continuous temples (for spreading fabrics along their whole width), and gripper temples (for holding the fabric by pressing together two jaws), the most widely used temples are of the roller type, having the roller embraced by the fabric, thus causing a friction of a variable value between the fabric and the roller. In material which shrinks only a little, and in lightweight materials, this friction is sufficient for holding the fabric. With other materials, inclined needle rollers are used at the foot part of the temple.

The actual construction of these conventional temples varies widely. For the purpose of simplification, such temples can be categorized in the following manner: single roller temples, multi-roller temples, temples with an upper housing, temples with a lower housing, temples for silk, for cotton, for wool, special temples, temples with a cylindrical roller, temples with a conical roller, temples with the positionof the roller axis parallel to the fabric, temples with the position of the roller axis inclined to the fabric, long temples, short temples, needle roller (ring) temples, etc.

For weaving synthetic materials, two basic demands must be fulfilled by the temples: I

a. the maintenance of a traverse pull upon fabrics of high shrinkability;

b. minimum tracing of the finished goods. When manufacturing fabrics of synthetic materials, and after dyeing the fabric with a grey or blue color, a temple trace reducing the quality of the fabri is visible upon using a wrong temple type. 4

The demand prescribed by a) is met best by tworoller temples which are designed in such manner that the mutual position of the front roller and the rear roller is adjustable. The overall shrinkage of the fabric is evenly distributed on both rollers.'

The demand prescribed by b) is met best by temples in which the axis of the roller is inclined with respect to the weaving plane. The transition of the fabric from the weaving plane to embracement of the roller is continuous and changeable.

The present invention has as its object the provision of a temple which meets the above demands to a maximum extent. The temple according to the present invention is formed of at least two mutually parallel temple rollers, of which one tangential plane is located in the weaving plane, and an angularly adjustable middle batten located between said temple rollers.

Further advantages and features of the present invention are described in the following specification and shown in the form of an exemplary embodiment in the accompanying drawings in which:

FIG. 1 is a plan view showing the location of the temple in the loom;

FIG. 2 is a diagrammatic representation in longitudinal section of the temple according to the present invention;

FIG. 3 is a transverse section through the temple shown in FIG. 2;

FIG. 4 is a view in perspective of a first exemplary embodiment of right temple and a heated selvage trimming loop;

FIG. 5 is a view in perspective of a second exemplary embodiment of right temple with weft cutting knives mounted between the temple rollers;

FIG. 6 is a view in perspective of a third exemplary embodiment of a right templewith a heated trimming loop mounted between the temple rollers; and

FIG. 7 is a view in oblique projection of an exemplary embodiment of an adjustable middle batten.

As shown in FIG. 1, the temples according to the present invention are mounted in a looms rear of the fabric selvage 2 at the

side walls

3 and 4 of the loom frame between the broad beam roller 5 and the slay 6 as near as possible to the point of beat-up of slay 6 for the purpose of holding the shrinking fabric 2 to a width corresponding to the width of the drawn-in warp 7.

The arrangement of the temple according to the present invention is shown diagrammatically in FIGS. 2 and 3. The temple rollers 8 have their axes parallel to the weaving plane of the fabric 2 and have their surfaces mounted tangentially thereto, the angle of embracement B of a roller by fabric 2 being determined by the adjustable middle batten 10 in "such manner, that the angle of embracement [3/2 of each of rollers 8 may be adjusted from zero to maximum. The transition of fabric 2 into angle [3/2 is continuous and takes place over a long distance, the end of temple roller 8 being above fabric 2, so that no abrasions of the fabric can take place. 7

A first exemplary embodiment of a right two-roller temple is shown in FIG. 4, the embodiment of the left temple being not different therefrom and thus, for the sake of simplicity, not being shown.

Temple rollers 8 are fastened by a holder 11 and by means of screws 12 in

slots

13 and 14 of a carrying plate 15. Slots 14 are longer in direction than slots 13, making possible a mutual displacement of roller 8 along its longitudinal axis. This is advantageous mainly with a very shrinkable fabrics 2. The carrying plate 15 is fastened by means of screws in slots 17 to angle iron 18. The slot 17 in carrying slate 15 makes its possible to to place the temple rollers 8 to a position as near as possible to the beat-up point of slay 6. Upon releasing a screw 19, by means of which an angle iron 18 is connected with a rectangular guideway 20 to a holder 21 for the temples. It is possible to move both temple rollers 8 in the direction upwards or downwards as required, for example, upon filling the loom or upon cleaning the temple rollers 8. It is necessary to displace thetemple holder 21 along the breast beam connecting piece 22 upon charging the width of fabric 2. For this purpose there is provided a connection by means of a screw 24 through a slot 23. The angle of embracement [3/2 of temple rollers 8 is determined by a middle adjustable batten 10 in the exemplary embodiment shown in FIG. 7. The central supportting batten 10 made in the form of a T section is sunk with one of its ends into the groove 25 of a displaceable angle iron 26 of U section which is mounted by screws 27 upon the supporting batten 28. The other end of the adjustable middle batten 10 is lifted or lowered as required by means of screws 29 supported in one of openings 30 in the bottom of member 26. This embodiment of the middle supporting batten 10 is obviously only one of many variations, which need not be further described.

The supporting batten 28 is made in the form of a flute and can act upon the complete lowering of the middle supporting batten l and the temple rollers 8, as a lower housing of the temple. lts lifted ends are thereupon situated above the lower tangential plane of the temple rollers 8, and increase the angle B of embracement of fabric 2 about the said temple rollers 8.

The supporting batten 28 is fastened by means of screws 31 and brackets 32 to the breast beam connecting place 22. Said batten can be made of one piece without connections and transitions leaving traces of the fabric. lts position need not be changed upon changing the width of the fabric 2. The holders 33 make possible its adjustment in the direction towards the reed of slay 6, or from the reed, as required, upon using reeds of various thickness.

The arrangement of the temple as shown in H0. 4 leaves enough space for mounting cutting knives or heated selvage trimming loops 34 and for the free passage of the cut or trimmed-off waste edge 35.

It is advantageous to mount the cutting knives within the space of the middle supporting batten between the temple rollers 8 as shown in FIG. 5. This makes it possible to achieve woven-in weft ends of zero or minimum length. In the middle supporting batten 10 a lower knife 36 is mounted which, in the case of zero length must be mounted below the fabric 2 with its blade towards the edge, i.e. in a direction reversed from that shown in FIG. 5. A swingable upper knife 37 is in engagement therewith said upper knife being mounted on a swingable control device of known design. For the purpose of the correct guiding of the waste edge 35 below the cutting knives 36 and 37, the front temple roller 8 must be prolonged into a continuing cylindrical part 38.

Instead of cutting knives 36 and 37, a heated trimming loop 34 may be mounted in the same space. The middle supporting batten 10 is provided with a recess 39 reaching as far as below fabric 2. Such an arrangement which is shown in FIG. 6 makes it possible to adjust the heat trimming loop 34 as far as into fabric 2, whereby melted selvages of zero length are achieved. There is then no necessity of another cutting trimming loop, nor is it necessary to perform the operation of trimming selvages in special machines apart from the loom.

Although the invention is illustrated and described with reference to a plurality of embodiments thereof, it is to be expressly understood that it is in no way limited to the disclosure of such a plurality of embodiments but is capable of numerous modifications within the scope of the appended claims.
