ABSTRACT:
The invention concerns a device for separating tape portions of mutually equal length from a tape of flexible material. Said tape is provided with a plurality of slots spaced at mutually equal distances, said slots extending obliquely relative to the longitudinal direction of the tape substantially over the whole width thereof, so that short unslotted edge portions are left at each tape edge. Said tape passes through a guide channel along a first bottom portion thereof and over a steplike ledge at its end and below an adjacent elongated member which resiliently presses said tape into engagement with a subsequent second bottom portion of the guide channel. Said elongated member and said second bottom portion end at a distance from one sidewall of said guide channel and when the tape is pulled forth in the guide channel with its trailing unslotted edge portions along said sidewall, the tape tab defined by the foremost slot and extending against the pulling direction is moved to a position at the side of said second bottom portion and is displaced downwards below said bottom portion, so that the corresponding unslotted edge portion is torn off and the opposite unslotted edge portion thereafter is ruptured.
