Patent number: 6763936Abstract: A chain conveyor formed from a plurality of modules or links (1a, b, c) connected together by pins c2a, b) which are inserted through holes (4, 4A) present in the modules or links (1a, b, c) and are prevented from escaping by axially counteracting elements (5) mounted in seats (6) also present in the modules or links (1a, b, c), in which the axially counteracting elements (5) present a flexible tang (5c) which, when the axially counteracting element is mounted in the seat (6), intersects an end portion (4A) of the holes (4, 4A) through which the pin (2a, b, c) is inserted, to thus prevent the pin withdrawing from the holes (4, 4A), such withdrawal however being enabled by deflecting the flexible tang (5).Type: GrantFiled: November 13, 2002Date of Patent: July 20, 2004Assignee: System Plast S.p.A.Inventors: Sergio Marsetti, Rodolfo Reatti

Patent number: 6561340Abstract: The present invention relates to a modular wall system for accumulation stations for conveying lines for products having a plurality of first and second components so that each of the first components have a face defined by a plurality of rollers, each one of the first components being structured and arranged so that it is attachable to another first component in end to end abutment and also attachable to another first component in face to face abutment. Each of the second components is selectively attachable to a first component.Type: GrantFiled: August 9, 2001Date of Patent: May 13, 2003Assignee: System Plast S.p.A.Inventor: Rodolfo Reatti
