Abstract
The invention concerns a winding device for taking up a paper web immediately after manufacture. The device comprises a carrier drum onto which the paper web is guided from one side (feed side); a winding rod with bearing journals; articulated levers which support the bearing journals in brackets and cause the winding rod with the rolled paper web to pivot around the carrier drum from a feed position into a pay-out position; a longitudinal cutter in the region of the winding-on side and upstream of the carrier drum for cutting the web into strips; a pressure roller for exerting contact pressure on the paper strips; and a support roller on the run-off side of the carrier drum in the pay-out region.

Winding device for the taking up of a paper web with a carrying drum (1) onto which the paper web coming from a feed side is brought up,
- with a winding core (2),
- with articulated levers which have forks and which swing the paper web around the carrying drum (1) from a feed position into a pay-out position,
- with a lengthwise cutter (3) provided in the zone of the feed side, engaged in front of the carrying drum (1), for dividing the paper web into paper strips,
- with a carrying roll (5) arranged in the pay-out zone on the pay-out side of the carrying drum (1),
- a rider roller pair (4.1, 4.2) for applying a pressure force upon the arising paper roll (7) is provided,
- to the rider roller pair (4.1, 4.2) there is allocated a suspension and contact pressure device (15),
- the rider roller pair (4.1, 4.2) and the suspension and contact pressure device (15) are swingable around the carrying drum (1) over a certain angle, in common with the winding core (2).
Winding device for the taking up of a paper web immediately following its production,
- with a lengthwise cutter for separating the paper web into paper strips,

- with a transfer unit for transferring the paper strips to the winding stations, in which two paper strips adjacent to one another are fed to different stations,
- each winding station comprises:
- a carrying drum (1),
- a pair of tension heads to which a drive is allocated,
- a guide arrangement for guiding the tension head pair with the arising paper rolls (7) from a feed position around the carrying drum (1) into a pay-out position, as well as for the returning of the empty tension head pair after delivery of the finished paper rolls (7),
- a rider roller pair (4.1, 4.1) for applying a contact pressure force to the arising paper rolls (7) and a suspension and contact pressure device (15) are swingable around the carrying drum (1) over a certain angle, in common with the winding core (2).
Winding device for the taking up of a paper web immediately following its production,
- with a lengthwise cutter (3) for separating the paper web into a plurality of paper strips,

- each winding station comprises:
- two carrying rollers,
- a rider roller pair (4.1, 4.2) for applying a contact pressure force to the arising paper rolls (7) is provided,
- to the rider roller pair (4.1, 4.2) there is allocated a suspension and contact pressure device (15),
- the rider roller pair (4.1, 4.2) and the suspension and contact pressure device (15) are swingable around the carrying drum (1) over a certain angle, in common with the winding core (2).
Winding device for the taking-up of a paper web immediately following its production,
- with a lengthwise cutter for diving the paper web into a plurality of paper strips,
- with two winding stations,
- with a transfer unit for transferring the paper strips onto the winding stations, in which arrangement two paper strips adjacent to one another are fed to different stations,
- each winding station comprises:
- at least two carrying rollers,
- a feed device for the bringing of the individual paper strips to the winding station from underneath, through the interspace between two carrying rollers adjacent to the one another,
- a pair of rider rollers (4.1, 4.2) is provided,
- to the rider roller pair (4.1, 4.2) there is allocated a suspension and contact pressure device (15),
- the rider roller pair (4.1, 4.2) and the suspension and contact pressure device (15) are swingable around the carrying drum (1) over a certain angle, in common with the winding core (2).
Winding device for the taking-up of a paper web immediately following its production,
- with a lengthwise cutter for separating the paper web into a plurality of paper strips,
- with a winding station which comprises the following elements:
- a stationary or horizontally movable carrying drum (1) over which the paper web runs,
- a winding core (2),
- the winding core (2) is installable into a winding-on position situated essentially beside the carrying drum (1),
- between the carrying drum (1) and the paper roll arising on the winding core (2), a linear force is adjustable,
- the nearly full winding core (2) is transferrable into a free winding position, in which preferably a squeeze-out roller is settable on the paper roll (7),
- a rider roller pair (4.1, 4.2) is provided,
- to the rider roller pair (4.1, 4.2) there is allocated a suspension and contact pressure device (15),
