Description

The invention relates to photographic equipment, namely, devices for transporting flexible tapes along a multi-track tract of a make-up machine.

The purpose of the invention is to reduce the size and increase ease of operation.

FIG. Figure 1 shows schematically a tape path of a tapping machine; in fig. 2 -. view A in FIG. one; in fig. 3- section BB in FIG. 2

The device consists of support strips 1 and 2, installed with the possibility of parallel mixing, relative to each other. Brackets 3 with bushings 4 are mounted on the plates, in which the holder 5 is placed. The holders 5 are made in the form of a plug with holes and a shaft 6. In the hole of the holder 5, an axis 7 is freely mounted, at the ends of which there are housings under bearings 8 composite rollers 9. On the axis 7 in the groove of the fork (holder) 5, the sleeve 10 is fixed, and on the end of the axis 6 of the holder 5, there are bushings 11 with a fork 12, which cooperates with the rotation stop 13 installed on the crown LiiTci iii 3.

Type A

The dimensions of the sleeve 10 and the groove of the plug are made such that the axis 7 with the rollers 9 has the possibility of axial movement due to the change in the distance between the strips 1 and 2.

The device works as follows.

The bending belt 14 (shown by a dotted line) is conveyed by a transport mechanism (not shown) to the rollers of the upper unit, then to the rollers of the lower unit, and so on along the entire path of the extension machine. In this way, the forks 5 with the axis 7 and the composite rollers 9 are rotated by a tape 14 in parallel vertical planes in the sleeves 4. In this case, the axes 7 with the rollers 9 are moved in the axial direction by an amount proportional to the distance between the upper and lower roller blocks, ensuring axial coincidence line of symmetry of the tape 14 at the transition between the rollers of the blocks.

The pins 12, interacting with the stop 13, prevent the rollers 9 from turning over in the process of charging the device with tape.

Claims (1)

TAPE LINE FOR A DRINKING MACHINE, comprising two parallel supporting strips, on each of which there are brackets with roller holders mounted for rotation relative to each other in parallel planes, characterized in that each roller made in the form of two housings mounted on an axis with a thrust bush located between them, and the holder is made in the form of a plug with holes in its ends, through which the axis p face, and the thrust sleeve is located in the groove of the fork, the axis of rotation of which is perpendicular to the axis of rotation of the roller, and is equipped with a rotation limiter.
