Description

The proposed folding machine is designed to bend the edges of the fabric when sewing it, which until now has usually been done by hand.

In the drawing of Fig, D depicts a front view of the machine; FIG. 2 is a side view of it; FIG. 3 is a view from above; FIG. on the side of the jaw for fading; FIG. 5 and 6 details.

Four bearings 2 are placed between two pillars 1, fixed on the platform 11 (Figs. 1, 2, 3), of which the two lower seats are tight and the two upper ones move up and down along the grooves on the inner surfaces of the racks. In the bearing, x 2, the rollers 3 are rotated, equipped at one end with gears 4. On the lower roller, the Maxi 5 is reinforced, due to the rotation of which the rotation in opposite directions of the rollers 3 occurs. for keeping the spring position between the uprights 1. At the top of the slat 7 there is another strap 8 with a cut hole for the clamping screw 9. At the ends of the slat 8 there are holes with bolts 10 holding it in place while the screw 9 is pressed. nakronshtey na 25 is attached to the platform 24 (fig. 2 and 4) with the posts 12 installed on it, with the axis 13 between them. On axis 13, a rod 14 is pumped, the other end of which is provided with a slot for an eyelet 15 of a bar 15 (FIG. B) provided with notches at the ends for giving it the desired position. Together with the strap 15, the shoe 16 can be lowered or raised, pressed against the material by a spring 17 si, which can be locked, if necessary, by pawls 18, for which springs 19 are intended to connect with the uprights 12 (Fig. 4). In order to delay the exit of the rod 14 from the axis 13, it is equipped with a spring 21 of the latch 20. The fabric guides 22 are located on the platform 24 with bending plates 23.

For actuation of the machine. two fingers are pressed on the pawl 18, thus freeing the bar 15, and i thus raise the entire device, which rotates on the axis between the pillars. Raising the device, put the matter in the guide 22, which must correspond to the width of the matter. Further, pressing the fingers on the latter, push it forward between the folding plate 23. As such, tucked the matter between the rollers, lowered it at; put it in place and let the car go. Bashiak 16, standing in place, falls on its lower part on the matter, the edges of which, bent under the action of the folding plates 23, fall on top of it. BpiaijiaH flywheel 5, get the rotation of both vadikov3, but in different directions. Rollers 3, tightly touching each other, at the same time dragging and clamping the pre-bent edges, the matter. The gap between the rollers is adjusted by the irim screw 9, which, passing through the upper bar 8, presses the pdaik 7, combined with the spring.

6, in turn, pressing with its ends on the upper subshir in which the axes of the upper shaft rotate.

The subject of the patent ..

A folding machine for fabric, provided with rolling rollers, bending longitudinal edges with plates, characterized using a shoe 16 between the folding plates 23, pressed against the material by a spring 17 and pivoting on the axis 13, to lock which shoe serve as a pawl-18.
