Abstract

Pin-feed platens used with pressure rolls to feed continuous-form paper do a poor job of feeding paper because the pin feed and pressure feed tend to feed at slightly different rates. This results in loss of engagement between the pins and holes.

Continuous Form Paper Feed

Pin-feed platens used with pressure rolls to feed continuous-form paper do a poor job of feeding paper because the pin feed and pressure feed tend to feed at slightly different rates. This results in loss of engagement between the pins and holes.

To relieve the effect of different feeding rates the platen 10 is periodically moved away from the pressure rolls 12. Pivoted end supports 14 and 16 of the platen are rocked by arms 18 and 20 connected to eccentrics 22 and 24 on a shaft 26 driven by means of a belt 28. The platen is driven by a belt 30 and gears 32, 34 and 36 mounted in the support 16.

This allows the paper to move slightly to engage the pins properly before the holes can be damaged.
