  • the secondary drive provided in the present case as a center drive 38 is along the second guideway parallel to the rails 34 traversable.
  • Carrying drum 12 serves in the present case as a pressure drum, whereby it for example via a guide carriage parallel to the rails 34 the secondary bearing 32 is movable.
  • the Carrier drum 12 and the winding roll 30 with associated drum 16 in proceed on the same level.
  • the line force in the winding gap 18 can in particular have a corresponding Pressure of the support drum 12 on the drum 16 or on this winding roll 30 formed can be adjusted in the desired manner.
  • a corresponding compensation of the increasing winding diameter can by a corresponding movement of the winding roll 30 can be compensated along the rails 34.
  • the jacket is the Carrier roller 16 continuously provided with holes 40 and an outer Suction box 42 can be sucked.
  • This suction box 42 lies with his Suction opening 44 the peripheral region not wrapped by the material web 14 the carrier drum 12 opposite.

He is on both long sides by provided in the area of the suction opening 44 with the support drum 12 cooperating sealing strips 46, 48 sealed to the outside. moreover are also corresponding on the two end faces of the suction box 42 Sealing elements provided.
  • the material web 14 is released from the support drum 12 and in derived a reject resolver 22.
  • FIG Drain area 50 of the support drum 12 provided sealing strip 48 at the same time designed as a scraper through which the guided over the support drum 12 Material web 14 or a performer of this material web 14 again is released from the support drum 12 (see also Figure 2).
  • the suction box 42 can also be formed on both sides by scrapers Sealing strips must be sealed.
  • the one provided in the discharge area 50 has at the same time as a scraper sealing strip 48 a parallel to the drum axis Axis 52 pivotable on a side wall 54 of the suction box 42 mounted base body 48 'and a scraper blade inserted therein 48 ".
  • the base body 48 ' is by two compressed air hoses 56, 58 in opposite directions acted upon.
  • the two compressed air hoses 56, 58 are arranged on opposite sides of the axis 52, whereby the sealing strip 48, which also serves as a scraper, passes through the compressed air hose 58 can be pressed onto the carrying drum 12 while through the other compressed air hose 56 away from the carrying drum 12 is acted upon.
  • About these two compressed air hoses 56, 58 is thus the respective contact pressure with which the sealing strip 48 against the carrier drum 12 is held, in particular also adjustable.
  • the suction box 42 is in the present Case via a connectable to a vacuum source 60, with suction openings 62 provided inner tube 64 can be subjected to negative pressure.
  • This inner tube 64 also extends in the present case Case at least essentially over the entire width of the machine.
  • the suction openings provided in the jacket of the inner tube 64 62 can in particular on the side facing the carrying drum 12 of the tube 64 may be arranged.

As a result of the carrier drum sucked in from the outside 12 is particularly the risk of uncontrolled self-performance of the performers or the entire material web 14 on the still empty drum 16 'or the winding roll 30 of an already tied Removed drum 16. A respective change of the seals is in the simplest possible way. An expansion of the support drum 12 is for this not necessary anymore. After the sealing strip 48 simultaneously as a scraper the additional scraper device previously required is also eliminated.
