PCT No. PCT/SE82/00298 Sec. 371 Date May 31, 1983 Sec. 102(e) Date May 31, 1983 PCT Filed Sep. 27, 1982 PCT Pub. No. WO83/01227 PCT Pub. Date Apr. 14, 1983.A feed mechanism for sheets of material or continuous webs in a printer or typewriter, comprising a pin wheel feed mechanism for the feeding of continuous webs and a friction feed mechanism for the feeding of sheets of paper as well as the webs. The pin wheel feed mechanism and the friction feed mechanism are coupled together in at least two separate units for the feeding of the webs. During feeding of the webs the frictional feed pressure is reduced compared to that prevailing during friction feed of the sheets when the pin wheel feed mechanism is inactive. |
