SYSTEM WITH TRAVELLING MEMBER Russian patent published in 1998 - IPC

FIELD: system with travelling member. SUBSTANCE: the system uses a rectangular travelling member, having parallel first and second sides and guide roller assemblies secured on them. Each assembly has rollers and a spindle, on which they are installed one after another for rotation irrespective of one another. The spindle is attached at a right angle to the first and/or second side of the travelling member respectively, the plane of rotation of rollers is perpendicular to the plane of the travelling member. Two fixed guides are available, the first of which is positioned on the first side of the travelling member, and the second one - on its second side. Each guide has supports passing in parallel and used to guide and hold the supports of the guide roller assemblies, the first of which is engageable with the first roller on one side, and the second one - with the second roller on the opposite side with respect to the point of engagement of the first roller with the first support. Relative layout of rollers of each assembly and of the respective supports holds the travelling member against movement in all directions, except for the preset one, by the guides with their supports. EFFECT: improved design. 5 cl, 17 dwg
