Patent DE-4006440-A1 (DE)
Inventor: STEFFL MANFRED DIPL ING
IPC: B29C55/16
Filed: 1990-03-01
Abstract: Conventional devices for stretching and fixing sheeting have a chain wagon (5) in which the clear distance between the running rollers has a low tolerance in order to obtain play in relation to the associated running surfaces of a guide rail. This results in vibrations and interferences, particular at increasingly high feed rates of the transport chain. To overcome these drawbacks, a clamping device with an adjustable running roller (7') is permanently clamped on the associated running surface (1'') of the guide rail (1) in function of the tension forces. The device is particularly suitable for stretching and fixing plastic sheeting.
