ABSTRACT:
A method and apparatus are proposed for the combined guidance, incorporating a register, of two continuously advanced foil strips, such as when attaching a foil cover strip to a lower foil strip including container-like recesses. The foil cover strip is preferably of aluminum and has printed legends which must be oriented precisely with respect to the container-like recesses of the lower foil strip. A marking is associated with each legend for scanning by a photo cell. The distribution of the legends and thus of the markings is somewhat closer together than the distribution of the container-like recesses. By stretching the foil cover strip, the distribution of the legends and of the markings can be adapted to the distribution of the container-like recesses. To achieve this, the foil cover strip undergoes a brief clamping in place during its continuous forward movement, during the course of which clamping the clamped area of the strip is distended mechanically, pneumatically or hydraulically to accomplish the desired stretching. A stretching apparatus is provided perform this method, substantially comprising an oscillating lifting press system. The oscillating lifting press system cooperates with a counterpart element. The foil cover strip is firmly clamped in a slip-free manner by clamping devices, so that within the clamped area round rods provided in the oscillating lifting press system and the counterpart element can stretch the foil cover strip.
