A separator unit suitable for being used in a cutting line of laminar materials into strips, of the type comprising an expandable shaft, a storage magazine for storing separator tools, which is operatively associated with an end of the expandable shaft, separator tools provided with ring nuts configured to allow the translation of the separator tools from the storage magazine to the expandable shaft, and vice versa, the separator tools being susceptible to being locked on the expandable shaft, and translation apparatus means configured to translate the separator tools along the expandable shaft. The separator unit provides for the expandable shaft to be provided with a first slit adapted to house a locking element with a knurling on its outwards facing surface and susceptible to translating in radial direction and provides for the ring nuts to have a counter-knurling on a length of their surfaces facing the expandable shaft. The knurling and the counter-knurling are configured to fixedly couple when the surface of the locking element is placed in contact with the surfaces of the ring nuts.

A score knife positioner includes a carriage bracket having a locating tab for receiving a score knife assembly. Linear bearings are attached to the carriage bracket and are configured to engage with a pair of guide rails. The linear bearings are offset from one another and located so that score knife positioners on either side of a particular score knife positioner can be nested together. The carriage bracket has a width less than a width of the score knife assembly and allows adjacent score knife assemblies to be positioned so that there is less than one-half inch between score knifes. Score knife positioners can be moved to a desired location and locked into place via a carriage brake attached to the carriage bracket.

A machine and a method to carry out workings on a sheet of a sufficiently rigid material is suitable to make containers. The machine includes a transverse working head guided by a first transverse guide member, one or more longitudinal working heads, each selectively positionable in a desired transverse position, guided by at least a second transverse guide member parallel to the first transverse guide member; and positioning mechanism configured to cooperate with each longitudinal working head in order to selectively position it in the desired transverse position.

A slitter having a first slide, a first driving rail, multiple round knife modules, a second slide, a second driving rail, multiple bottom cutter modules and at least a controller is provided. The round knife module is arranged on the first slide, each round knife module is provided with a first actuator geared with the first driving rail. Each bottom cutter module is arranged on the second slide corresponding to a position of one of the round knife modules, each bottom cutter module is provided with a second actuator geared with the second driving rail. Each first actuator and the corresponding second actuator are electrically connected with the corresponding controller. The round knife module and the bottom cutter module are respectively moved by individual first actuator and second actuator. While the round knife module and the bottom cutter module are moving, material could be fed between them.

A score knife positioner includes a carriage bracket having a locating tab for receiving a score knife assembly. Linear bearings are attached to the carriage bracket and are configured to engage with a pair of guide rails. The linear bearings are each staggered with respect to linear bearings of adjacent carriage brackets and located so that score knife positioners on either side of a particular score knife positioner can be nested together. The carriage bracket has a width less than a width of the score knife assembly and allows adjacent score knife assemblies to be positioned so that there is less than one-half inch between score knifes. Score knife positioners can be moved to a desired location and locked into place via a carriage brake attached to the carriage bracket.

A separator disposing portion 15 is provided with a ball screw 22 and an arm 23. The arm 23 is a member which comes into contact with a holder 17 and a separator disk 18, thereby allowing them to move. The arm 23 is provided with a chuck portion 30 which is connected to a piston 29 and can be fitted to a chuck pedestal 27. The chuck portion 30 comes close to or moves away from an expansion/contraction shaft 16 in association with expansion and contraction of the piston 29. Further, the chuck portion 30 comes into contact with an outer circumference surface of the holder 17, a side surface of the holder 17 and a side surface of the separator disk 18 in association with movements of the piston 29 and a driving portion 26.

The invention relates to a punch for punching polymeric motor vehicle components, in particular bumpers, comprising a machine frame (1), at least one device for fixing a polymeric motor vehicle component (2) on the machine frame (1), and at least one punch device (3), wherein the punch device (3) comprises at least one punching tool (4) and at least one punching die (5). According to the invention, the punching tool (4) and/or the punching die (5) is/are fastened to a receiving device (6) of a movable carrier (7, 8), wherein the carrier (7, 8) has at least one further receiving device (6) for fastening at least one further processing apparatus (9, 10, 20, 30), such that the punch can be set to a new, different processing step involving the further processing apparatus (9, 10, 20, 30) by a movement of the carrier (7, 8).

A top tool and a bottom tool which can be set relative to one another along an axis perpendicular to a workpiece plane are provided in an apparatus for punching and welding plastic parts. A punch die and a sonotrode are fastened to one of the tools.
