Description

The invention relates to a machine for trimming lining edges at the shoe opening of worn-out footwear at the stitch between the upper and the lining near the - connecting the latter - Seam. When making shoes, it becomes known after sewing the lining together with the Shank left a lining edge protruding beyond the upper edge of the shank, which improves the adhesion of the shoe is achieved on the last. This lining edge is then with the completion of the shoe With the help of a special trimming machine, which has an up and down moving knife, cut off. This must be done very carefully and requires a great deal of attention and attention from the worker Skill so that the vibrating knife does not damage the * 5 curved shaft edge and possibly the edging strip injured.

It has now been proposed to use the cutting machine with one that slides along the shoe To provide guidance for the knife, but this suggestion was not yet fully satisfactory because it was due to the up and down swinging knife for the actual guide piece again required special system parts and yet there was a risk that the seam connecting the shaft to the lining would be damaged became.

The present invention therefore takes a different approach and uses one for different cutting operations Known horizontally swinging knife with cutting edge. According to the invention is on the seam, connecting the upper and the lining, sliding along the stitch between the upper and the lining sensing guide attached to the knife. This training made according to the invention is extremely simple and still ensures that the lining edge is trimmed without the risk of damaging the shaft or seam will.

The guide stands over the cutting edge of the knife about the distance between the shaft edge and the upper one The shaft seam comes out, and the operator therefore has to keep the cutting depth practically no longer to be careful at all, so that the trimming without the risk of damaging the shaft is faster and safer.

In the drawing, the device designed according to the invention is shown in different views.

A knife holder 2, on which a knife 3 with a cutting edge, sits on a vibrating lifting carriage 1 6 is attached. A conventional knife guide 4 is also provided. According to the invention is at the Knife 3 attached a protective guide 5, which over

the cutting edge 6 protrudes a little. This protruding part of the protective guide 5 is between Upper and lining of the shoe introduced Ms to the stitch; the height of the preceding part must therefore be the The distance between the seam and the edge of the socket. The cutting depth of the knife 3 is thus due to the Stitch along sliding protective guide 5 set so that any cutting of the knife into the shaft and is optionally switched off in the edging strip.
