Description

A feature of this folding machine system is that it spreads the material in two directions with the help of a special device shown in FIG. 3 and 4.

FIG. 1 shows a general view of a folding machine; FIG. 2 is a top view of the cutting part of the device.

The material travel is as follows: matter, from the platform of the machine (Fig. 1), thrown over several rollers, is clamped between the legs a b. The end of the material (when the machine starts working) is clamped with a load of 7 at the stop 5. When moving to the left, the machine approaches the stop A (Fig. 1) and touches the protrusion 4 behind the rod 5, pulling the knife b (Fig. 3). Upon further movement of the protrusion 4, / meeting the lever and deflecting it, it lifts the load /, which, when the support 2 comes off the lever 3, falls into the notches of the legs a and b and presses the material to the table. At the same time, the rod 3 is released from the protrusion 4 and the knife b is quickly returned by means of a spring and drum 7 to its original position, cutting the taaterial. The compressed moment of the machine has a reverse stroke, with an emphasis 2 and a protrusion 4

freely pass the lever 3 p. rod 5. The lever 8 freely moves and rolls on the protrusion to the stop A when the machine moves towards the stop A, but when the machine moves backward it deflects to the left together with the legs a and 6, which at the same time rise depending on the accumulation of material transfer. At this time, the lever 9 (ft. 3 and 4) turns the legs a and 6 over by 180 ° (Figs. 3 and 4), prepared the flooring material for the stop b, where the described machine operation is repeated, etc.

The subject matter of the invention.

A device for mechanically laying and cutting fabric, consisting of returning a moving carriage, mechanisms for clamping the ends of the fabric and knives for transverse cutting of the latter, characterized by the application for passing the fabric as the carriage moves and pressing the legs a and b (Fig. 3 and 4), made by turning the lever 9 to 180 °, in order to prepare the fabric for the flooring during the reverse course, the carriage.
