Abstract

This invention relates to a method for manufacturing end brushes and allows for an increase in labor productivity. The wire is fed along a fixed flat pattern followed by a winding of the pattern with the base wire (PO) of threadlike pile material to form loops from it. The carrier tape (LN) is supplied, the software carrying the loops is combined with the LF, the LN is wound with the pile loops attached to it onto the rotating mandrel. The supply of the software and the LV is carried out in two parallel streams on opposite sides of the fixed template. Winding filament pile material is carried out with the capture of both streams ON. Cutting loops lint lead along a line symmetrical with respect to the streams of software. Winding the LF with a pile of loops produced with the formation of two brushes. 2 Il. e s

This invention relates to bristle production.

The purpose of the invention is to increase productivity.

Fig. 1 shows a diagram of the device on which the proposed method is carried out; Fig. 2 is a schematic of a device for adjusting the density of the winding of the turns of the pile.

A device for carrying out the method is placed on the body of a turning-screw-type machine tool.

The method of manufacturing the face brushes comprises the operations of feeding the base wire 1 along the fixed flat pattern 2 followed by winding of the pattern 2 with the base wire 1 of filamentary pile material 3 to form loops from it, feeding the carrier tape 4, aligning the base wire 1, the loop loops , with the carrier tape 4 and the winding of the carrier tape 4 with the lint loops 3 attached to it on the rotating mandrel 5

The wire base 1 and the carrier tape 4 are fed in two parallel streams on opposite sides of the fixed template 2, the winding of filament-like pile material 3 is provided with the capture of both streams of the base drawing 1, and then cutting the loops of the pile along a line symmetrical with respect to the streams of the wire base 1, and the winding of the carrier tape 4 with the pile loops attached to it on the rotating mandrel 5 is made with the formation of two brushes 6.

The mandrel 5 is made interchangeable. Using interchangeable mandrels of various shapes (round, square, triangular, etc.), a different shape of the brush body can be obtained.

The filamentous material of the pile 3 is pre-wound on the packages 7, which are then fixed on the disk 8 of the device.

By varying the speed of rotation of the disk 8 or the number of packages 7 installed on it, it is possible to produce a multi-layer winding of the turns of the pile.

Adjustment of the winding density of the turns is also carried out in the manner shown in FIG. 2. For this, at the end of the shaft 9, in addition to the interchangeable mandrels 5, the mandrel 10 with high flanges is attached, which has the same shape as the mandrels 5, for example triangular. On this mandrel, the end of the chain 11 is secured, which winds from the braked drum 12 and passes between the sprockets 13 and 14 and the driving adjusting sprocket 15. When turning on the machine spindle, the chain 11, the thickness of which corresponds to the thickness of the carrier tape 4, rotates the sprocket 15 The sprocket 15 transmits rotation to the disc 8 through the overloading gear 16. After the winding of the carrier tape has been completed, the chain 11 is rewound to the drum 17 by means of an actuator for moving the caliper.
