Description

The proposed stanszh is designed to cut spun laces into segments of the same length.

In the drawing game. 1 is a side view of the machine; FIG. 2 is a front view of it;

FIG. 3-top view of it; FIG. 4-knife device; FIG. 5 kind of gear

The laces run through the holes 1 in the board 2, which are above the upper pair of rollers 3 and 4. The laces, between them, are gripped by another pair of rollers 5 and 6 (lower) and tensioned because the pulley 8 on the roller b is smaller than the pulley 7, from which he gets the movement. H0 roller 4 sits a replaceable gear 9, which, through parasitic gear 10 and gear 11, rotates roller-2, on which the gear 12 sits with a full number of teeth. When skipping the desired value

lace teeth bevel gear 12 rotate bevel gear 13

and the roller makes part of the turnover. Since the roller 21 could continue to move by inertia, then the spring 15 prevents this, the finger of which enters the through hole of the roller 20 and only when the finger 16 presses the spring 15,

the roller will turn on a part of the turn, for

the spring finger will go into the hole on the opposite side of the alik 21. On the roller 20 sits knife 14 (Fig. 4) with blades on both sides and,

part of the turn, he cuts two laces on both sides. The cut laces are arranged in parallel as follows: by means of the cam 17 and the lever 18, the clip 19 is swung; when the V is passed through the desired length of the lace, the clip 19 with the right edge: pushes the lace to the right, which, during the departure of the bracket 19, to the right rests on its surface. When the bracket 19 is on the right side, the rest of the cut cord, having passed through rollers 5 and 6, falls down, i.e. lies on the left side of the bracket. Pulleys 7 and 8 can be replaced with cones to adjust the tension of the lace.

The subject matter of the invention.

1. A machine for cutting spindles: shoelaces, different in using two located one above another: a pair of rollers 3 and 5, rotated from the transmission station and used to feed the boards passed through the hole 1. the board installed above them, 2 shoelaces to the rotating knives, 14, made in the form of korea and fixed on a vertical roller 20, for turning; What roller on the floor of a revolution, at certain intervals, is the gear of gear 12, 13, in which the bevel gear 12 has no

the total number of teeth sits on a horizontal roller 21 carrying the finger 16, which serves to deflect the spring 15 attached to the board 2 and fitted with a spade at the free end entering the through hole of the vertical roller alternately on either side. 2. When machine tool for p. -1 application

for parallel laying of the cut laces of the lever 18, pivotally attached to the frame of the machine and driven into oscillatory motion by means of the cam 17, d the pinch roller 21, which the lever 18 carries at the lower end a brace 19, laying the lace as it is fed by the rollers 5.
