Description

 / The proposed invention concerns

. stretcher machine devices

 and. finishing raw tatnyh skin, equipped with leg bilami moving under

 centrifugal effect radially in the grooves. associated with - between a skin-trimming disks

 b arab on. In order to secure the ends; the treated leads, one of the beats, according to the invention, is made detachable .. ,,

. The schematic drawing of FIG. 1 shows one of the marked disks of a drum; FIG. 2-view of the machine

. above, FIG. 3 is a cross-section of a split bar that serves to secure the ends of the treated skin, FIG. 4-bottom half of it. beat, fig. 5 - device detail

I machine. .;.;

The specified machine mainly consists of -r dil 18 (fig. 2), whose axes 16 are dispersed, in naz $ 1 (fig. 1) of disks 13 of rotating ba,. Rabana 1 machine.

The skin is supposed to be superimposed on the beats: and with its conp, 9ll is fixed in one of the beats, for which the latter is made of two detachable parts L7 (Fig 3) fastened to the axles of its axis 16 and the help of bolts 3 and linings 2, of

which one is provided with squares Ai and 4 with teeth entering the recesses of the other.

For the convenience of releasing the ends of the skin after processing, the "ends of the Ifi axis of the split beat || are made of rectangular cross section, so that the bullet moving along the grooves 14 does not turn, i.e. the bolts 3 do not change their position.

The machine is driven by a belt drive through the pulley 21 of the bulk 15 of the drum 1. Under the action of centrifugal force 18, it is moved and the slots 14 of the discs 13 are pressed and the skin covering them is processed (smoothed, creased, stretched, and f. P. ).

To communicate the discontinuous movement disks 13 (with the purpose of controlling their rotational speed), the shaft 15 is connected by a belt drive 5.6 (Fig. 2) to the axis 10, provided with the arms 7 regulating the rotation of the disks 13 (Figs. 2 and 5) with weights and pressed spring 9 coupling 8, fastened to the rod 22, transferring the strap alternately then to the working pulley 21, 10 on the IDLE-20.

At the set speed limit, the levers 7 are consumed by the vehicle and the 31 | ufta 8 is moved, compressing the spring 9 and turning off the bets, then when the speed of rotation of the drum 1 decreases, the spring 9 doesn’t move the belt onto the working pulley 21.

Thing . .g, "

1. Bets dl. stretching and trimming raw leathers with beams moving radially in an axial direction, interconnected disks of a skin drum, characterized in that one of the rollers 18

 ,

. consists of detachable parts 17, skrelluyutsya with the axles of its axis 16, rectangular sections, using bolts 3 and lining 2..

2. Form of implementation of the aforementioned in and. 1 machine, characterized in that | p; | messages to discs 13 with supporting machining; impelled, skin by prelvivnogo movement, shaft 15 of discs is connected with a belt transmission 5.6 with axis 10, equipped with rotation arms regulating discs 18 with 7 levers and pressed spring 9 with clutch 8, fastened with phthanga 22, which translates belt alternately on working and idle pulleys 20 and 2.1
