Description

The invention relates to a device for mechanically laying a fabric consisting of a carriage for rolling fabric, clamping devices and a circular cutter for cutting fabric. In the proposed device, the upper part of the carriage, equipped with brackets for placing rolls of fabric in them, is pivoted on rollers in order to measure the direction of the pile of fabric during the return stroke of the carriage.

In FIG. 1 shows a side view of the device with a partial cut; FIG. 2 - its top view; FIG. 3 is a front view of it.

The device (Fig. 1) consists of an iron carriage with four running wheels, on which it can move along the cutting table manually or by means of additional tools from the motor 9, by frictional transmission to one of the carriage axes. The friction clutch acts only when the transmission is inactive on the stroke of the screw, on which the special nut 5 moves (Fig. 2).

The upper part of the carriage (Fig. 2) is provided with a wooden disk 2 having a slot for passing the fabric. The disk can be rotated on four rollers 4 fixed in bearings in order to change the direction of the pile during the return stroke of the carriage. On the disk, there are two crochetes 17 in which the shaft 18 rotates with a roll of cloth (Fig. 3).

The fabric from the roll passes through the upper and lower guide rollers, through the slot in the disk, and is fixed on the ruler 3 (Fig. 1). When moving forward, the ruler 3 fits under the clamp 15, the clamping part of which rises to skip the ruler 3 with the help of two cams 16 (Fig. 2) sliding along the curve of the clamp body, turning off the fabric clamping device at a certain moment. When the carriage reverses at any place, the fabric is cut as follows: between the disk 2 and the base of the carriage, a screw 5 is moved by the screw set in motion from the motor 9, resting on the guides 10. On the nut 5 there is an area where a motor 6 is mounted, the disk knife 19 is set in motion. The coil springs mounted on the uprights 14 while the carriage is moving support the whole arrangement in the upper position. When the carriage stops, p. by means of a switch and a sliding contact, motor b is set in motion, thereby achieving rotational movement of the disk knife 19; the forward movement of the nut 5 along the screw is carried out from the motor 9 by switching on the friction gear.

In order to cut, it is necessary to lower the disk knife 19, which is achieved by means of the flywheel 7, during rotation of which the disk knife with the screw and guides is lowered, and the knife enters the slot on the ruler 3 and cuts off the required piece of fabric. ,

Subject invention

A device for mechanical laying of a fabric consisting of a carriage for rolling fabric, clamping devices and a circular cutter for cutting fabric, characterized in that the upper part of the carriage 2, provided with brackets 17 for placing a roll with a fabric with a cutout for passing the fabric, is made pivoting on the rollers 4 in order to change the direction of the pile of the fabric during the return stroke of the carriage.
