The invention relates to textile and light industry equipment, namely, devices for transverse cutting of a material with a fringe.

The aim of the invention is to improve the reliability of the device.

Fig. 1 schematically shows an proposed device; figure 2 - this cross, view syrhu; on FIG. 3 - section A-A in FIG. 2; figure 4 - section 1B-B in Fig, 2; in FIG. 3, the position | of the grips: a) when the grips approach the plates; b) when entering the plates | between the grips; c) at the exit of plates from | under the grippers.

I The device contains a mechanism for moving the material, implemented in the; View of the carriage 1, mounted on Controllers 2, carrying the bar 3 with elastic plates embedded in it; Us 4, having removable ends at the ends: material grips 5 made in the form of spring-loaded jaws, The force of the clamp is adjusted by screws 16 mounted on the slats 7, and: the stops 8 are fixed at the edges of the slat 3.

The mechanism for fixing the COCO material from the fixed stop 9, rigidly fixed on the guide axis 10, on the swing arms 11 of the installation of the pressure roller 12, the levers 1 by means of the pull 13 and the spring-loaded lever 14 with the roller 15 are connected to the program disk 16, on a fixed stop 9, a plank 17 is installed with the clamps 18 and the guides 19 carrying the spring-loaded pushers 20 -c with the plates 21 rigidly attached to them.

The fringe orientation tool with respect to the cutting line consists of two parallel movable combs 22 and 23 located symmetrically with respect to the fixed separation axis 24, which has a groove in the cutting zone. Combs 22 and 23 are rigidly fixed by means of levers 25-28 on shafts 29 and 30 connected by a neck 31 and 32 to each other. Means for fixing the position of combs 22 and 23 are made in the form of a disk 33 rigidly fixed on a shaft 3D and interacting with the brake a pad 34 with an electrically magnetic actuator 35, and the means for adjusting the tension of the fringe is performed in the form of a counterweight 37 placed on the lever 36 of the orienting means

the orientation of the fringe and rigidly fixed shaft 29 and by means of the pull 38 and rocker arm 39 with the roller 40 interacting with the program disk 16.

The mechanism for receiving the cut material is made in the form of a flat table 41, mounted on rails 42 with the possibility of reciprocating and moving, and has a spring-loaded rod 43, which through the pull 44 and the lever 45 with the roller 46 contacts the program disk 16 The program disk 16 is connected via a shaft 47, sprockets 48 and 49, a chain 50, a shaft 51, and an asterisk 52 to the kinematic mesh with the drive of the carriage 1,

The cutting tool mechanism (knife) consists of a disk knife 53, which engages into the groove of a dividing fixed axis 24 and is fixed to a shaft of an engine 54 mounted on a carriage 55 moving on a guide 56 by means of driving rollers 57, which by means of shaft 58, pulleys 59 and 60 and the belt 61 are connected to the engine 54.

The device works as follows.

The material with fringe 62 (Fig. 5.a) is tucked under the clamps 18 so that the edge of the material hangs from the front of the fixed stop 9. When the engine 63 is turned on, the carriage 1, by means of pulleys 64 and 65, belt 66, shaft 67, sprockets 68 and 69, chains 70 and 71, sprockets 72 - 76, 52, chains 76 and 77, begin to move to the fixed stop 9. The material grips 5 run over the plates 21, while the stops 8 press. pushers 20 and plates 21 begin to move simultaneously with grippers 5 (Fig. 5b). The material 62, located between the grippers 5 and the plates 21, forms a loop in the front part of the abutment 9. During the return stroke of the card 1 (Fig. 5c), the grips 5 move, release the plates 21 and clamp the material 62 in the looping zone and transport it to the flat table 41. The program disk 16 by means of an asterisk 52, a shaft 51, asterisks 48 and 49, a chain 50, rotates, interacts with spring-loaded levers 14 with a roller 15, which through pull 13, the swing lever 11 lowers the pressing axis 12 , material 62 begins to round combs 22 and 23. If there are 62 teaching materials weaving with fringe dressing fringe on combs 22 and 23 and due to increasing tension of material 62 between grips 5 and combs 22 and 23, it is released from under grips 5, while the released edge of material 62 is placed on a flat table 41. The program disk 16, rotated, by means of a yoke 39 with a roller AO, ti 38, a lever 36 with a counterweight 37, a shaft 29, a garage 32 and 32, a shaft 30, levers 25-28 simultaneously spreads the comb 22 to the sides symmetrically to the dividing axis 24 by an amount equal to the length fringe, microswitch 78, entering into engagement with the program disk 16, includes an electromagnetic magnetic drive 35, which presses the brake shoe 34 to the disk 33

and fixes the position of the combs 22 and I

23, the motor 54 is simultaneously turned on, which by means of pulleys 59 and 60, the belt 61, shaft 58 rotates the drive rollers 57 and the disk knife 53, while simultaneously moving the carriage 55 and cutting the fringe of material 62 with the disk knife 53. Micro switch 78 exits from engagement with the software disk 16 and turns off the electromagnet 35. and the engine 54 and the block 34 comes out of contact with the disk 33. The next operation of the microswitch 78 is provided by changing the direction of rotation of the engine 54 with a circular knife 53 .. and the direction of movement of the carriage 55. Further, the carriage 1 begins to approach the fixed stop 9, and the cut material 62, located on a flat table 41, by means of a lever 45 with a roller 46 in contact with a program disk 16, 44, a spring-loaded gatanga 43 is shifted away from the combs 22 and 23 and placed on the flat table 41. With further rotation of the program disk 16, the paddles 22 and 23 begin to converge, the pressure roller 12 rises, the flat table 41 moves, and the claws 5 slide onto the plates 21, and the cycle repeats.

The proposed device is reliable in operation.
