1. Arrangement for operating a contact roller (7) with the following features:
- a linear motor drive (14) for position changing is assigned to the contact roller (7), the linear motor drive (14) acting preferably on the bearing points (20) of the contact roller (7), there is furthermore a force control means (400) for the linear motor drive (14), and the linear motor drive (14) can be operated on the one hand as a damping means and on the other as a contact pressure means for producing a contact pressure force for the contact roller (7), there is a location sensor and/or a speed sensor and/or an acceleration sensor and/or an actual value and/or speed and/or acceleration detection and/or determination stage in order to detect and/or determine the corresponding location, the speed and/or the acceleration of a secondary part (18) of the linear motor drive (14), which part can be moved relative to an at least relatively stationary primary part (16), the force control means (400) is built such that an inherently definable or preselectable contact force for the contact pressure force of the contact roller (7) with another roller (1), preferably in the form of a take-up roller (1) or a bale (5) which can be rolled thereon, can be modified with consideration of a force correction value which can be derived from the actual values of the position value and/or speed value and/or acceleration value of the secondary part (18) which can be moved relative to the primary part (16).

Abstract
An improved arrangement for operating a contact roller (7) and an associated method, characterized inter alia by the following features: a linear motor drive (14) is allocated to the contact roller (7) in order to change positon; a force adjustment device (400) is provided for the linear motor drive (14); a suitable sensor is also provied in order to determine speed or acceleration.

14. Process for operating a contact roller (7) with the following features:
-
a contact roller (7) with a variable position is triggered via a linear motor drive (14) for changing its position, a force control means (400) is used, via which the linear motor drive (14) can be triggered on the one hand as a damping means and on the other as a contact pressure means for producing a contact pressure force for the contact roller (7), a location sensor and/or a speed sensor and/or an acceleration sensor and/or an actual value and/or speed and/or acceleration detection and/or determination stage is used to detect and/or to determine the corresponding location, the speed and/or the acceleration of a secondary part (18) of the linear motor drive (14), which part can be moved relative to an at least relatively stationary primary part (16), and by the force control means (400) an inherently definable or preselectable contact force for the contact pressure force of the contact roller (7) with another roller (1), preferably in the form of a take-up roller (10) or a bale (5) which can be rolled thereon, is modified with consideration of a force correction value which is derived from the actual values of the position value and/or speed value and/or acceleration value of the secondary part (18) which can be moved relative to the primary part (16). - View Dependent Claims (15, 16)
