The proposed machine consists of a chimney frame 7 (Fig. 1-3), placed on the frame. In the side walls., The frames on the inner side are made guide grooves / 7, in which they are moved to the cutters with the help of endless chains 4, driven by handles J2, frames of one type or another, with blanks attached to them. At the rear end of the frame Y there are two bearings 25, in which the swing frame 2 is rotatably fixed. In the bearings of frame 2, axes 27, 22 and 23 are placed, of which axes 2f and 22 serve to place rotating mills on them to machine the workpiece and interchangeable in accordance with the operation. The axis 23, on one end, carries a belt pulley coming from the counterdrive, and on

by a friend. The end is provided with a toothed pinion, connected to gears, pushed onto axes 27 and 22, thereby resulting in rotation when the axis 23 rotates.

The manufacturing process of the spoons on the proposed label is divided into seven operations, and the successive forms of the preform b shown in fig. 22, which it will have after the “corresponding operations, are shown in FIG. 23-29.

In order to carry out the first operation, b-b (Fig. 22) is placed in raincoats in rows, parallel to the axes 21 and 22, to the frame 31 (Fig. 4-6), where they are fixed with clips a. The frame 31 is then inserted with OWN ridges into the guide grooves // of the frame 7 and moves along the direction of the arrow B (Fig. 1-3) to the cross (27 by means of the chain 14, With the passage of the blanks with the frame 31 under the axis 27, frame 2 Together with the axis 21 it is lowered with the help of the fucker 14 in such a way that, respectively, the mills mounted on the axis 21 (Fig. 18) are selected in the blanks, and the grooves are formed into the shape indicated in Fig. 23.

For the production of the second and third operations (Fig. 24, 25) on the axis 27 (Fig.) (The milling cutters shown in Fig. 19 are mounted and on the axis 22 of the milling cutters shown in Fig. 20. The workpieces to be processed are strengthened by means of clamps c (fig. 7-10) in frame 4, after its frame 4, as in the production of the first operation, advances to the axis 22 which by the handle 24 rises, and the cutters (fig. 20) mounted on it, in the workpieces are selected the recesses corresponding to the second operation. The third operation is performed directly behind the second cutters (Fig. 19), mounted on the axis 27, p The tel 27a of which, when the frame 4 is moving, is guided with the TIOM of the copier 41 (Figs. 7, 8, 11), mounted on the frame 4.

For the production of the fourth and fifth operations (Fig. 26, 27), the workpiece d h (Fig. 25) is carried out under the mills in the frame 37, where they are fixed (Fig. 4-6) and have a rib, and For this operation, workpieces for the subcap are provided with linings e (Figs. 26 and 27).

For the execution of the thumbs and the seventh operations (. 26, 29), the blanks (Fig. 27) are placed in frame 5 (Fig. 14-16), where they are stacked so that they are perpendicular to the axis 27-23. In this case, the spoons of the spoons are placed on the convex cushions 57 and pressed against the top by concave plates 52, and the cuttings of the spoons are backed up by the shoulders 53 or 5 when processing from both sides (Fig. 21). mounted on the axis 27, 27a of which, when advancing the frame 5, is guided by a cam 55, When performing the seventh operation (Fig. 29) produced by the mills (Fig 21), mounted on the axle 22, the roller 22a of the latter is guided similarly to the sixth operation by a cam 55 .

With the appropriate selection of cutters and copiers, the machine described can also be used to make wooden heels, toys and other shaped wood products.

The subject matter of the invention.
