TAB INSERTER

摘要

Apparatus arranged to insert a tab between two sheets of a stack of paper, to serve as a marker, has a driven roller (24) and a pinch roller (26) with the tape (12) extending therebetween. The pinch roller (26) is mounted on a rocker arm (25) having at its other end a stud (27), the arm (25) being spring urged to engage the stud (27) with the tape. When the tape is to be fed, the rocker arm is pivoted to release the brake effect of the stud (27) and engage the pinch roller (26) with the drive roller (24). The arm is mounted on a housing (14) which may be pivoted away from the tape path to facilitate tape loading or the clearing of a jam. A rotary cutter assembly (34) is mounted downstream of the drive roller (24), the cutter assembly having a bar (35) mounted for rotation within a sleeve (37), the bar having a transverse slot (36) through which the tape passes. The downstream edge of the slot (36) co-operates with an edge of the sleeve (37) to provide a shearing action on rotation of the sleeve.
