Abstract: A film winding system (1) for a film stretching unit (110) comprises a film entry area (3) through which a film web (2) to be wound can be fed to the film winding system (1). A first winding station (4) is configured in a winding position to wind the film web (2) into a film bale (5). A contact roller (6) and a measuring roller (8) are provided, the contact roller (6) being arranged adjacent to the first winding station (4) in the winding position and being configured to guide the film web (2) to the first winding station (4). The measuring roller (8) is arranged before the contact roller (6) in the movement direction of the film web (2) and is configured to guide the film web (2) to the contact roller (6). A first adjustment device (10) is provided and configured to move the measuring roller (8) relative to the contact roller (6) along a travel path in such a way that a degree of wrapping over which the film web (2) covers the contact roller (6) can be varied.

Abstract: A film winding system is disclosed having a first winding station which is configured in a winding position to wind the film web into a film bale. A contact roller and a compensating roller are provided, wherein the contact roller is arranged adjacent to the first winding station in the winding position and is configured to guide the film web to the first winding station. The compensating roller is located before the contact roller in the direction of travel of the film web and is configured to guide the film web to the contact roller and to set a film tension. A first adjustment device is provided and configured to move the contact roller towards the winding station or away from the winding station, thereby enabling the setting of a specific contact pressure between the contact roller and the film bale. The first adjustment device comprises a slide system or an adjusting spindle.

Abstract: The invention relates to an improved transporting unit for a transporting device, in particular for a transverse, longitudinal, and/or simultaneous stretching installation, wherein transporting units (KT) can be moved along a guiding and/or supporting rail by means of a clip unit (KL) and a drive unit (AT) connected to the clip unit, is characterized by the following features: the clip transporting unit (KT) or the clip unit (KL) and/or the drive unit (AT) has, for example, a volume or weight fraction of at least 60% that consists of a forged part (ST) and/or is composed of a forging blank (SR).

Abstract: An improved gripper with a toggle lever arrangement is characterized by, among others, the following features —the gripper comprises a gripper lever which is pivotable with respect to a gripper holder around a gripper axis, —the gripper lever is configured as a toggle lever and comprises in addition a first and a second toggle lever leg which are pivotable relative to each other around a toggle lever axis, —in addition a force application unit is provided which acts on the second toggle lever leg pivotable around the toggle lever axis and/or on the toggle lever flap, —the force application unit is thereby configured such that during pivoting of the gripper lever from the release position into the closed- and clamping position thereof, the toggle lever flap initially touches down on the side of the gripper table lying away from the material web while prefixing the material web in this region, before the toggle lever flap reaches the final closed- and clamping position thereof during the remaining pivoting proc

Abstract: The invention relates to an improved method for lubricating transport systems or parts thereof, especially for lubricating guideways and rails in elongating systems. The inventive method can be realized in that the lubricant film continuity comprises the equation: X=(lubricating active time/lubricating inactive time)≧100 and/or the lubricant film continuity comprises the equation: Y=(lubricating active time/(lubricating active time+lubricating inactive time))≧10%.
