摘要： Unwinder for paper converting, comprising a support (1) adapted to support a reel (B) from which a web of paper material is unwound and comprising dragging means acting by contact on said reel (B) and adapted to impose a rotation of the reel coil about the respective longitudinal axis (x) with a predetermined speed, the diameter of the reel (B) varying while the latter rotates. The dragging means have a variable configuration. The unwinder comprises reconfiguration means adapted to vary the configuration of the dragging means on the basis of the instantaneous diameter of the reel (B) and control means (5; EU) adapted to control said reconfiguration means such that the contact between the reel (B) and control the dragging means takes place on a contact area (200) having an angular extension (a) substantially constant while the diameter of the reel (B) varies.

摘要： A device for automatically unwinding web-shaped materials (8) from a master roll (3), and to a method for operating a device of this type are disclosed. The device has an infeed arm (2) and a first drive unit (6), wherein the master roll (3) by way of the winding core (4) thereof is rotatably mountable on the infeed arm (2), and the first drive unit (6) serves for introducing a driving force into the master roll (3). In order for high productivity to be achieved, the unwinder (1) has an outfeed arm (13) to which a second drive unit (14) for introducing a driving force into the master roll (3) is assigned, wherein the master roll (3) during an unwinding procedure is transferable from the infeed arm (2) to the outfeed arm (13). The material web (8) is then unwound from the master roll (3) which is mounted on the infeed am (2) down to a predefinable minimum diameter, wherein during the ongoing unwinding procedure the master roll (3) is subsequently transferred to the outfeed arm (13) and thereon is further actively unwound, wherein a new master roll (3′) is received by the infeed arm (2). Unwinding without interruption is thus enabled.

摘要： A belt device includes a belt wound around support rotators, to travel as the support rotators rotate; a belt contact member on a rotation shaft of one of the support rotators, to contact an end of the belt and move in an axial direction of the rotation shaft with the belt; a displacement member on the rotation shaft and including an inclined face to move the one support rotator, to move in the axial direction as the belt contact member moves; a guide to contact the inclined face and restrict a moving direction of the displacement member; a shaft support rotatably supporting the one support rotator and the rotation shaft; a restriction member to restrict movement of the one support rotator and the rotation shaft; and an elastically deformable intermediate member between the shaft support and the restriction member, to prevent the shaft support from contacting the restriction member.
