ABSTRACT:
The disclosed apparatus implements a method of joining two sheets of heat transfer paper into a single sheet almost twice as wide for use in heat transfer printing of extra wide cloth. The paper is withdrawn from source rolls and passed along first and second respective web paths with a very slight overlap between the papers. A glue station applies a speed controlled amount of glue to the overlap region of one paper and the edges of the paper are brought together in the desired overlapping relationship. The thus joined paper is passed through compression rollers and wound onto a resilient rewind roll. Edge sensors in each of the web paths maintain the overlap alignment of the paper paths and tension sensors in each of the paths maintain a desired level of tension. A video camera imaging system provides the operator with periodic video images of a magnified region of the overlap so that proper registration between the patterns on the respective papers can be maintained. Should the pattern loose registration, the operator can pulse a brake on one of the source rolls which has the effect of quickly moving the paper back into alignment.
