Patent number: 6689041Abstract: A folding jaw arrangement (11) at a lateral surface (9) of a product-carrying cylinder (10) in folding apparatuses. The folding jaw arrangement (11) includes a stationary folding jaw part (13) and a movable folding jaw part (14). Formed therebetween is a gap (12) into which a folding means (5) of further cylinder (4) co-operating with the product-carrying cylinder (10) plunges during the cross-folding of products. In the process, the product to be cross-folded passes from the further cylinder (4) to the lateral surface (9) of the product-carrying cylinder (10) and is held thereon by the folding jaws (11). The movable folding jaw part (14; 29, 40) is provided with resilient regions (20, 27) via which the product is brought into and held in contact (15) with the stationary folding jaw part (13) of the folding jaw arrangement (11).Type: GrantFiled: November 20, 2001Date of Patent: February 10, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Serge Lanvin, Jean Francois Robert, Philippe Robin

Patent number: 4265438Abstract: The disclosure relates to a tucker cylinder which cooperates with a folding cylinder to fold a sheet. The tucker cylinder is rotatable about a first axis and has a cylindrical outside surface and a circular end face. A tucker blade is connected to a carrier which is rotatable about a second axis within the tucker cylinder and parallel to and spaced from the first axis about which the tucker cylinder rotates. The carrier has a slot extending radially of the second axis, and a member fixed to the end face of the tucker cylinder slidably engaging the slot for transmitting rotary motion of the tucker cylinder to said carrier. An arcuate opening is formed in the end face through which the member extends. The arcuate opening is coaxial with the first axis of rotation of the tucker cylinder, and the member is adjustably positioned in the opening to adjust the timing of the motion of the tucker carrier.Type: GrantFiled: July 24, 1979Date of Patent: May 5, 1981Assignee: Societe MarinoniInventor: Serge Lanvin
