DEVICE FOR CHANGING DIRECTION OF CHAIN OF DIES WITH RUNNING ROLLERS FOR TRANSPORTING MOVING MATERIAL WEB Russian patent published in 2017 - IPC B29C55/16 B29C55/20 

FIELD: transportation.

SUBSTANCE: device has the running rollers (2) for transporting the moving material web, the sprocket wheel (4) and the guide rail (5) equipped with at least two running tracks (6.1, 6.2) for the running rollers (2) of the dies (1). The two running tracks (6.1, 6.2) are arranged respectively at two sides of the guide rail (5), turned away from each other, parallel to the rotation axis of the sprocket wheel (4). The guide rail (5) has at least one curved portion (5.2) for changing the chain direction. In the area of the curved section (5.2) of the guide rail (5), there are connecting elements (8, 9, 10) through which the guide rail (5) is connected to the direction change device (3). Several connecting elements (8, 9, 10) are made so that at least part of the curved portion (5.2) of the guide rail (5) is capable of radial displacement relative to the sprocket wheel (4).

EFFECT: providing the direction change of the chain of dies in the radial or the tangential direction and the reduction of various disturbances in the direction change area.
