Appl. No.:

7/752395

Inventors:

Robert A. Crimmins - Algonquin IL

International Classification:

B65H 508

US Classification:

Abstract:

A sheet feeding apparatus (10) and method are disclosed that are fast, efficient, easy to set up and involve a minimum number of components. The sheet feeding mechanism (10) includes a first gripping member (20) comprised of two first suction cups (21) and a second gripping member (40) comprised of two second suction cups (41). The first suction cups (21) are moved along a first path (P1) between a first position and a second position by a first guide means (25). The second suction cups (41) are moved along a second path (P2) between a third position and a fourth position by a second guide means (60). Vacuum means (22,42) are connected to the suction cups (21,41) for picking up, holding and releasing sheets (TS). The first suction cups (21) pick up a sheet (TS) and transfer it to the second suction cups (41) which take the sheet (TS) to a lamination unit (LU1,LU2).

US Classification:

219471

Abstract:

A heated roller assembly (10) is disclosed having a rotatable roller (12). The roller (12) has a generally cylindrical section (20) with an outer diameter D and includes an inner insulative layer (36) thereover, a conductive layer (38) over the inner insulative layer (36), and an outer insulative layer (40) over the conductive layer (38). The roller assembly (10) also has an inwardly projecting conical portion (22) adjacent the cylindrical section (20) of the roller (12) with the inner insulative layer (36), conductive layer (38) and outer insulative layer (40) respectively thereover. A portion (A) of the conductive layer (38) on the conical portion (22) of the roller (12) is exposed. An external contact body (14) has at least one electrically conductive outer surface (46) that projects towards and contacts the conductive layer (38) of the conical portion (22) while piercing an imaginary plane P1 formed by an extending outer diameter (D) of the cylindrical section (20). A wire (18) having one end connected to the outer surface (46) of the contact body (14) delivers electricity to heat the roller (12).
