A pinning device for the electrostatic pinning of a film on a chill roll is disclosed having a first coil unit, a second coil unit, a pinning region situated between the coil units, a high-voltage source as well as at least two electrodes. At least the first electrode of at least two electrodes is strip-shaped. The electrodes run from the first coil unit to the second coil unit in the pinning region and high voltage is applied to both electrodes by the high-voltage source.

Pinning device, casting unit as well as stretching unit

A line for producing a cast film is disclosed having a slot die, a chill roll, an electrode assembly, an insulator assembly, a sensor device, and a control device. The electrode assembly is arranged between an impingement area of the cast film on the chill roll and a removal area. The insulator assembly is arranged between the electrode assembly and the chill roll shell. The sensor device continuously determines the left and right cast film edge. According to the determined left and right cast film edge the control device moves the insulator assembly in such a way that the insulator assembly is arranged: a) between the left end face of the chill roll and the left cast film edge; and b) between the right end face of the chill roll and the right cast film edge.

System for producing a cast film, and film stretching installation with such a system

An improved longitudinal stretching unit is disclosed, in addition to the installation position or operating position (A) for the assembly to be replaced, a standby position (D) and/or standby station at which a further assembly is kept on standby. The standby position (D) and/or the standby station is arranged and/or configured in relation to the longitudinal stretching unit such that the further assembly provided at this standby position (D) and/or standby station, already before the installation at the operating position (A), is brought or can be brought to operating temperature or at least to a preheating temperature that is higher or less than 30° C. lower than operating temperature.

Longitudinal stretching unit and method for replacing an assembly exposed to wear in a longitudinal stretching unit

An improved pressure roller arrangement, in particular for a stretching system, and a corresponding method for operating such a pressure roller arrangement are distinguished, inter alia, by the following features:

Pressure roller arrangement, in particular for a longitudinal stretching system and an associated stretching system and a method for operating such a pressure roller arrangement
