摘要:
An apparatus (1) for winding-up a metal strip (2) into a coil (3), includes a clamping pair (22) formed of a deflection roller (23) and a pressure roller (24) and located in front of the coil (3) in a material flow direction (10) so that the strip (2) is retained under tensional stress with respect to the coil (3) and is so bendable that the strip (2), which is provided with a corresponding pre-bend, is firmly wound into a coil (3). The apparatus further includes a first bending roller (35) pressable against the deflection roller (23), and arranged in front of the clamping pair (22) in the material flow direction (10), and a further roller (36) adjustable relative to the deflection roller (23) and arranged behind the clamping pair (22) in the material flow direction (10), with the pressure roller (24) and both bending rollers (35, 36) being so displaceable relative to the deflection roller (23) that an end region (45) of the strip (2) is additionally curved to form the pre-bend dependent on an end diameter (48) of the coil (3).

The invention relates to a method and a device for the rolling or winding of strip having an equal thickness over the strip width, in which the tension in a strip length portion limited by rolls, winders, or control, guide or deflecting rollers is measured by means of a measuring roller. In order, in this case, to obtain more accurate measurement values and keep disturbing stresses away from the measuring point, between the measuring roller and an assembly (roll, winder, or control, guide or deflecting roller) causing disturbing stresses in the strip, a partitioning device for absorbing the disturbing stresses is arranged.

A system for controlling multiple wire feed motors for use in a welding-type system including a push motor controlled to operate at a target wire feed speed and a pull motor disposed in a welding torch controlled to apply a target torque to the fed welding wire. Such a system eliminates shaving and bird nesting of welding wire.

The invention relates to a method for winding a metal strip (1) into a reel with a winding mandrel (2), to which the metal strip (1) is routed through a pair consisting of a first and a second driver roller (5, 6), at least one of which is driven. The method is characterized in that a difference between the strip speed (VB) of the metal strip (1) and the speed) (v5, v6) of the driver rollers is adjusted on the basis of measuring, from measurable process variables, the strip speed and the speed (v5, v6) of at least one of the driver rollers (5, 6).
