Abstract
A winder apparatus for a papermaking machine for winding-up a paper web onto a reel-spool, comprising an endless sieve or filter band arrangement which is guided over guide rolls, one of which serves as a drive roll. The band arrangement drives the reel-spool and the paper web which is wound thereon. As the drive roll there can be used the outermost guide roll viewed in the direction of driving of the reel-spool.
Claims9
A winder apparatus for a papermaking machine comprising:
- a reel-spool for winding up an infed paper web thereon so as to form a paper roll;
- an endless band arrangement for guiding the paper web onto the reel-spool by taking-up said web prior to the web contacting said reel-spool and for winding said paper web thereon in the form of said paper roll;
- guide means for guiding said endless band arrangement such that said band arrangement wraps about part of the reel-spool and the paper roll wound thereon over a part of the circumference thereof and thus places such reel-spool or the paper web wound on such reel-spool into rotation;
- means for supporting said reel-spool against the band for rotation thereby, the support means being constructed for movement of the reel-spool in a direction transverse to its longitudinal axis away from the band as the diameter of the paper reel on the reel-spool increases;
- said guide means constituting only guide rolls for exclusively guiding the band arrangement;
- said guide means guiding the band arrangement such that it contacts the reel-spool and the paper roll wound thereon essentially only laterally and from below;
- and
- one of said guide rolls serving as a drive roll.
