摘要
The invention relates to a nip force control system in a reel-up gear for a paper machine comprising a pair of primary arms (6, 7) and secondary arms (8, 9) for supporting and positioning a tambour core (2, 3) at the paper web winding operation as well as at the so-called change-over procedure when the tambour core is replaced. Each of the arms are connected to a hydraulic cylinder (10, 11) for positioning the arms and the primary-as well as the secondary arms are provided with load cells (12, 15) for measuring the nip force (F) for respective arm against the tambour core (2, 3). The control system also includes load cells (17) in the holding bracket (4) of the tambour core for measuring the additional force from said holding bracket. By this location of the load cells close to the measuring point an improved nip force control is obtained, especially during the critical change-over procedure.
