The invention relates to a device for attaching the severed parts of a band to one another. The trailing edge of a first terminating material band which is subjected to a treatment or to an operation in its downstream portion is connected to the leading edge of a second starting band. Included are a frame equipped with a means for the rotatable support of a supply roll or web for the first and second material bands and two cooperating, parallel pinch rollers. Each of the bands is guided along one of these rollers. A number of idler rollers are incorporated in the paths of the bands between each supply roll or web and the associated pinch roller. A device as described above comes in various embodiments, especially in relation to bands which are provided on both sides with an adhesive paste or adhesive tape.
Depending upon the intended use of the material band (usually used for printing purposes), there exists a need to connect two successive band ends, e.g., by either overlapping or abutting their edges. This task imposes a high degree of care and precision on the machine operator who is called upon to carry out this task.
