Patent number: 4501510Abstract: 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.Type: GrantFiled: May 31, 1983Date of Patent: February 26, 1985Assignee: Facit AktiebolagInventor: Leif H.

Patent number: 4462531Abstract: A tractor for a web feeding assembly has a chassis providing a pair of apertures extending therethrough and a belt extending thereabout. A drive pulley mounted in one of the chassis apertures is engaged with the driven surface of the belt and has an aperture therethrough receiving the drive shaft. Convexly arcuate belt support means cooperates with the drive pulley to define the web drive path for the belt therebetween, and a cover on the chassis overlies the belt and web drive path. Belt tensioning means is movably supported on the chassis below the drive path for resiliently biasing the belt against the guide means. As a result, pressures on the belt during operation of the tractor tending to produce deflection away from the cover are resisted by the belt tensioning means to maintain a rectilinear drive path for the web tightly against the cover.Type: GrantFiled: September 10, 1982Date of Patent: July 31, 1984Assignee: Data Motion, IncorporatedInventor: Alan F.

Patent number: 4118179Abstract: An elongatable endless belt passes around four rollers and, in so doing, passes adjacent to the heated surface of a U-shaped platen which has its edges adjacent to two of the rollers. The surface of the belt which faces the platen is in driving engagement with a film coming from a recording means. One of the noted two rollers is driven faster than the other so that the belt moves the film along the platen surface and leaves one edge of the latter at a higher speed than that at which the belt arrives at the other edge of the platen surface. Therefore, the belt progressively elongates and moves along the film as it is moving the latter along the platen surface.Type: GrantFiled: December 8, 1976Date of Patent: October 3, 1978Assignee: Honeywell Inc.Inventor: Dale O.

Patent number: 4010883Abstract: A thread delivery device, particularly for use with a texturing device, is described wherein an endless belt runs over two freely mounted rollers on a pivotable support. In the operative position of the support, the belt between the rollers contacts a power driven cylinder over a predetermined wrap angle. In this position, an adjustable abutment keeps a spring loaded belt guide element out of contact with the belt. However, when the support is swung to an inoperative position in which the belt is withdrawn from the driving cylinder, the abutment ceases to be effective so that the guide element, which is carried by a pivotally mounted arm to which the spring is applied, engages the belt and takes up the slack that would otherwise appear due to the elimination of the wrap on the cylinder. The spring may be connected either to the support or to a fixed part.Type: GrantFiled: October 15, 1975Date of Patent: March 8, 1977Assignee: Herberlein & Co. AGInventor: Helmut Ritter

Patent number: 4002280Abstract: This invention provides a U-shaped pathway for cut film and prints as the cut sheets are automatically moved in a prescribed manner, path and speed through a processing tank or tanks. This transport is between rollers which are spaced from each other sufficiently so that any potential squeezing or pressing on the emulsion surface of the film is safely absent. Large rollers are arranged in three vertical columns and provide the down and up travel path of the film. At the bottom of this transport path a large roller provides an inside guide for the film. A series of small rollers provide an outer guide path for the U-shaped transport section of film. These small rollers are driven as are all the other rollers but this outer U-guide is formed of short rollers arranged in an intermeshed pattern to provide a closely guided contour. Short small rollers are carried in spaced array on common shafts.Type: GrantFiled: May 12, 1976Date of Patent: January 11, 1977Assignee: Colenta American CorporationInventors: Kenneth R. Coleman, Hans G. Steinebach, H. Werner Waden, Paul Zamek

Patent number: 3998453Abstract: A conveyor apparatus for transporting sheets in a longitudinal direction along a transport path comprises a plurality of guide rollers arranged in axially spaced parallel relation and extending transverse to the direction of sheet transport. An endless belt means is provided having a lower run thereof coacting with the guide rollers to capture a sheet between the lower run of the belt and the guide rollers for advancing the sheet in a transport path. Selected ones of the guide rollers are positively driven and have their axes lying on an arc of slight curvature extending between axes of a first and a last guide roller with the arc curved upwardly towards the transport path. This arrangement provides a slight curvature to the lower run of the belt means to increase the frictional force exerted on the sheets for positive transport of the sheets in the transport path.Type: GrantFiled: May 19, 1975Date of Patent: December 21, 1976Assignee: Firma Mathias Baurele GmbHInventor: Wilfried Dorer
