Abstract
The present invention relates to a method of production and an arrangement for feeding and guiding web materials in laterally separate paths from a web supply to a machine for producing packing blanks. More specifically a web guide is disclosed, capable of controlling web materials in laterally separate paths from a side by side storage to be advanced in parallel paths through the machine and to be separately or simultaneously processed into packing blanks.
Claims15
An arrangement for guiding a web material in a feed direction, comprising:
- a frame having a horizontal member extending transversely to a feed direction;
- and
- at least one pair of guide-rails running from said horizontal member in the feed direction and being laterally separated from each other and in parallel with each other,
- each guide-rail in said pair of guide-rails comprising
- a flexible upper guide-rail strip and a flexible lower guide-rail strip,
- the upper and lower guide-rail strips made of flexible material,
- the upper and lower guide-rails running mutually separated from an entrance end to an exit end, and
- the upper and lower guide-rail strips being separated horizontally at the entrance end and spaced vertically at the exit end, providing therebetween a curved, continuous passage for a longitudinal margin of the web material.
