The invention relates to light industry and may find application in the manufacture of hats.

The purpose of the invention is the expansion of operational capabilities.

The device for trimming the edges of the headgear fields contains a table 2 mounted on a vertical drive shaft 1 for accommodating headdresses and a holder with a cutter (with a disk but a tool for them; a 3 mounted for radial movement relative to the axis of the table 2 and kinematically connected by a drive 4 The holder is made in the form of a two-armed lever 5, the cutting tool 3 is fixed on one shoulder of the lever 5 by means of a hinge 6, and the other is connected with the drive 4 of the table 2, while the axis 7 of the lever is movably mounted section along the axis 2 from its drive and the hinge 6 is coupled with

4 by means of a flexible shaft 8, the lever 5 is connected to the rotary sleeve 10 by means of a hinge 9. The lever 5 is connected to the drive by cams 11-13 and a transmission lever having a rod 14, a lever 15, a rocker 16. Cam 11, a rod 14 and the lever 15 serves to rotate the bushings 10 and the lever 5 .. The cam 12, the rocker 16 and the axis 7 serve to move the lever 5 in the vertical plane. The cam 13 is connected to the flexible shaft 8 by means of the pusher 17, the Cam 13, the pusher 17 and the shaft 8 serve to rotate the relative tool 3 relative to the hinge 6. The adjustment of the spatial movement of the lever 5 by the tool 3 depending on the size of the headgear on the front line is done by changes in the gear ratio of the lever mechanism by moving the support 18, the gear 1) 1 to 16 and the support 19 of the rod 14, the cams 11-13 are located on the shaft 20 which is driven by the electric motor 4 through the gearbox 21. The kinematic shaft 20 and associated transmission 22 (transmission ratio 1: 1) with the shaft 1, which is

table 2 with hats fixed on it.

The device works as follows.

Headdress fields are trimmed according to a given profile by a rotating disk knife 3 located on the axis of the electric motor. The table 2 with the headgear fixed on it rotates synchronously with the shaft 20 on which the cams are located. The cam 11 acts through the rod 14 on the lever 15 fixed on the rotary sleeve 10. Together with the rotation of the sleeve 10, the lever 5 is rotated in the horizontal direction, thereby changing the distance of the cutting tool 3 from the table axis 2. The cam 12 acts on the rocker 16 , having a movable support 18, and through the axis 7 - on the lever 5, carried out its movement relative to the hinge 9 in ver-. ticking plane, thereby changing the height of the cutting tool relative to the surface of the table 2.

Thus, with the help of two cams, a spatial cutting tool is specified, corresponding to 3, to the profile of the floor of the headdress. The cutting point of Hell is on the same axis with the hinge 6, with which the tool is attached to the lever 5. To cut the field perpendicular to its plane (Fig. 2 and 3), the tool rotates relative to the lever, 5 V the hinge 6. When rotating, the cam 13 acts on the pusher 17 and through yal 8 on the lever 5. Depending on the headgear pasiMepa, the gear ratio of the above-mentioned lever mechanisms changes due to the movement of the supports 18 and 19 with the help of appropriate screws.

This device cuts off the edges of the headdress fields of any configuration and different (front and rear) velgchins, without breaking their shape (i.e., not bending), thus achieving full preservation of the shape obtained during the pressing process.
