摘要:
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 The paper is withdrawn from source rolls and passed along first and second respective web paths with a very slight overlap between the papers.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.

A tabbed film strip comprising a film portion and a tab portion secured together in parallel adjacent edge relation by a connecting tape overlapping the film and tab portion and adhesively secured thereto in an arrangement leaving a major area of the film portion and tab portion uncovered throughout their lengths. Apparatus to form this product and to carry out a process of making it comprises a housing which supports individual feed supplies for the film portion and the tab portion and which also supports a feed supply for the connecting tape. The tape has pressure sensitive adhesive on one of its surfaces for securement to the film and tab portions. Forming mechanism is supported on the housing and has guide grooves therein as well as guide rollers and a hold-down arm associated therewith arranged to place the film portion and tab portion in parallel adjacent edge relation and to secure these two portions together by means of the tape. The film portion and tab portion, after leaving the forming mechanism, pass over a power driven drum which pulls the film and tab portions, as well as the tape, through the forming mechanism for the formation of the tabbed film strip. This drum is arranged to feed the completed film product to other mechanism upon demand of the latter.

The invention relates to a method and apparatus for producing a material web of synthetic textile material for conversion into table-cloths. Here, two material webs produced according to standard procedure are joined along their respective side edges to a material web folded to a V shape for obtaining a total width on the produced web that is greater than the maximum width of a web produced by standard procedure. The inventive apparatus includes two reels (1, 2) on which are would webs (3, 4) of standard manufacture, which may be rolled off the reels and into mutual proximity with the aid of a roll nip (6) disposed after the reels, there also being a folding plate (8) for folding a third web (5) into a V shape which may be joined to both webs (3, 4) along their respective juxtaposed side edges by its free side portions (12, 13) to form a material web (11) having a total width which is greater than the maximum width of a web produced by standard procedure. A web (11) produced in accordance with the method and apparatus includes at least three webs (3, 4, 5) spliced to each other along their respective side edges, at least one web (5) having its free side portion (12, 13) overlapping and joined to the longitudinal edges (9, 10) of the juxtaposed webs (3, 4).
