11613037 · 2023-03-28 · ·

A cutting unit comprising a cutting drum, a drum knife, a counterpart knife, and a double-joint controller that controls swiveling about a first joint, which swivels the counterpart knife between a cutting position and a waiting position, and swiveling about a second joint, which permits adjustment of a knife gap that forms between the counterpart knife and the drum knife in the cutting position. The drum knife is disposed on a circumference of the drum such that rotation of the drum guides the drum knife past the counterpart knife to cut a label when the counterpart knife is in the cutting position. In the waiting position, the counterpart knife is out of active engagement with the drum knife. The second joint permits adjustment of the knife gap such that the knife gap remains adjusted independently of swiveling about the first joint.

To provide a half-cut double-sided tape from a double-sided tape with a release-liner commercially available in the market by means of a simple process without contacting a cutter blade directly to an adhesive layer when making the half cuts in the half-cut process. The invention includes: a processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner; a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length are held on the release liner; a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer. A cut trace has a fully cut region in the width direction of the double-sided tape on the release liner and a non-cut region in the width direction of the protect release paper tape, so that the peeling is facilitated.

Cutting machine with blade depth adjustment

A cutting machine has a cutting support for material to be cut, with a vertically movable blade bar which bears a blade for cutting the cut material located thereon. A cutting drive is for vertically moving the blade bar. A blade depth adjustment is for vertically adjusting the blade bar relative to a vertically movable drive element of the cutting drive. The blade depth adjustment includes a deflection lever which is pivotably mounted about a horizontal axis on the blade bar. The drive element can be articulated thereon at a first radial distance to the horizontal axis. An adjusting mechanism may act on the deflection lever at a second radial distance to the horizontal axis, for rotating and fixing the deflection lever.
