Abstract

A rotary press to print patterns on support strips includes a drive for driving the support strip lengthwise at a defined speed; a supply for strip material of the patterns to be applied to the strip located laterally to the lengthwise drive and direction of the support strip; a transfer device for transferring the patterns from the strip material to defined locations on the strip; another drive for driving the strip material through the transfer device intermittently with the defined speed of the support strip. Strip material reorientation elements are arranged along the path of the strip material to modify its direction from transverse to the support strip to the same direction thereof and to deliver the support strip material and the support strip to a transfer device where transfer occurs. Various length and speed controls associated with the strip material deliver the same to the transfer section at a selected speed. A device joins successive reels of the strip material, preferably without interruption of the delivery of strip material to the transfer device, preferably by use of storage disposals for the strip material.

Dependent claims

A rotary press for printing patterns on a support strip comprising:

a driveable support to drive the support strip lengthwise at a selected speed;
a supply for supplying at least one strip material with a pattern thereon;
the supply for the strip material is arranged laterally of the support strip and laterally of the lengthwise drive direction of the support strip;
a transfer device shaped and positioned for bringing the support strip and the strip material together and for transferring patterns to the support strip at defined locations;
an intermittent drive operable on the strip material for driving the strip material through the transfer device intermittently and at the speed of the support strip;
the intermittent drive being operable for driving the strip material from the supply in a direction transverse to the lengthwise direction of the support strip;
and
strip material redirection devices positioned after the supply for modifying the direction of the material strip after the material strip leaves the supply and before the material strip passes to the transfer device, from a supply direction transverse to the lengthwise drive direction of the support strip to a transfer direction of the patterns that is parallel to the lengthwise drive direction of the support strip.
