An apparatus for marking and scoring an insulated wire or cable is disclosed. The apparatus includes a housing enclosing a portion of a wire path, wherein the insulated wire or cable moves along the wire path through the housing; an upper splined gear rod and a lower splined gear rod within the housing; an actuator connected to the upper splined gear rod, wherein the actuator raises and lowers the upper splined gear rod; and wherein the actuator when lowered presses the insulated wire or cable between the upper and lower splined gear rods.

A method for manufacturing a material strand assembly for a vehicle. The method includes: extruding strand material in an extruder so that an extruded material strand is produced; monitoring the quality of the extruded material strand so as to detect faults of the extruded material strand; in case of a detection of a fault, cutting out the fault from the material strand and re-joining cutting end faces, thus producing a joint, so that a faultless material strand is produced. The cutting-out step is conducted such that any two adjacent joints are at a minimum joint distance from each other. The faultless material strand is stored in a storage unit so as to produce the material strand assembly. The extruded material strand is passed through a first strand accumulator between the extruder and the cutting arrangement and through a second strand accumulator between the cutting arrangement and the storage unit.

The invention relates to a system (10) for improved introduction of a separating device (40) into a flattened film tube (2) of a blown film line (1), with a cutting device (20) for severing only a first tube side (2.1) of the film tube (2), in particular the film tube (2) which has not yet been flattened. Furthermore, the invention relates to a blown film line (1), as well as a method (100) for producing and providing at least two film webs (6).

An extrudate transport apparatus comprises a free floating roller assembly, wherein the roller assembly controls a rotational pitch of a cylindrical green ceramic extrudate as the green ceramic extrudate moves longitudinally from a first location to a second location within the extrudate transport apparatus. The free floating roller assembly has a predetermined effective weight and comprises a contact roller having a deformable outer surface for frictionally contacting an outer surface of the green ceramic extrudate in motion adjacent thereto, while maintaining a constant contact force upon said green ceramic extrudate.
