Abstract

Illustrated is a drive and aligning mechanism for taking a sheet 8 which has been delivered by a sheet feed mechanism 10 and translating it laterally as well as progressively, forwardly at the same time to align the sheet 8 against alignment reference edge 12. This feed and transport is accomplished by a caster arm drive mechanism illustrated in Fig. 2.

Caster Drive and Aligning Mechanism

Illustrated is a drive and aligning mechanism for taking a sheet 8 which has been delivered by a sheet feed mechanism 10 and translating it laterally as well as progressively, forwardly at the same time to align the sheet 8 against alignment reference edge 12. This feed and transport is accomplished by a caster arm drive mechanism illustrated in Fig. 2.

Caster arm 14 supports rotatably a pulley 16 on its outboard end. Pulley 16 is provided with a drive loop 18, which is fabricated of a material such as rubber or silicone and provides a driving surface 20. Driving surface 20 engages sheet 8 and pinches sheet 8 between driving surface 20 and backup roll 22. Backup roll 22 is supported on pivot arm 24 that is, in turn, supported on pivot member 26 which is grounded to the machine. Pivot member 28 likewise provides pivotable support for caster arm 14 and a drive connection between input belt 30 and input drive pulley 32. Input drive pulley 32 rotates driving pulley 34 to provide the driving motion to belt 18.

As a sheet of paper 8 is delivered to the aligning mechanism, the caster arms 14 have assumed positions as illustrated in Fig. 1. The paper is then grasped by the pinch point formed between follower wheel 22 and drive wheel 16 and belt member 18, and projected in a direction of feed as indicated by arrow 36. As sheet 8 engages aligning edge 12, as indicated by outline 38 in Fig. 1, the forces exerted on feed point 20 cause cas...
