Verfahren und Vorrichtung zum Verbinden von Materialbahnen

摘要

The invention relates to the unwinding of material strips (4), especially paper or cardboard strips. According to prior art, the end of a running material strip (14) is connected to the beginning of the strip (19) of a new winding roller (1) in the following manner: The running strip (14) is severed from the rest of the roller (17). The end of the severed, running strip (14) is held by means of a splice element (9) while the rest of the roller (17) is exchanged for a new full winding roller (1), whereby a paster tab (20) is attached to the end thereof. The end of the running strip (14) is subsequently pressed against the paster tab (20) in order to produce a pasted connection. According to the invention, a second paster tab (18) is attached to the end of the running strip (14) before the pasted connection is produced. Said second paster tab (18) produces a second pastered connection when the end of the running strip (14) is pressed against the beginning of the strip (19). A connection is thus produced which has no or only minimally protruding non-pastered remaining parts of the strip.
