Abstract:
1. An apparatus for winding a paper web from a rotatable drum onto a driven spool which supports a reel, said apparatus comprising: a frame; said frame including: a base having a first and a second end; a stand extending from said first end of said base for rotatably supporting the drum so that the paper web is guided by the drum; a further stand extending from said second end of said base; a carriage slidably supported by said base such that sliding of said carriage between said first and second ends of said base is permitted; a moving device extending between said carriage and said further stand for moving said carriage relative to the drum; a reel in position control device controllably connected to said moving device for selectively moving said carriage towards and away from the drum such that when the reel supported by the driven spool is mounted on said carriage and the paper web is guided by the drum onto the reel, the paper web is controllably wound onto the core; said stand extends upwardly from said first end of said base; said stand includes: a first portion; a second portion disposed spaced and parallel to said first portion so that the drum extends between said portions and is rotatably supported by said portions; said further stand extends upwardly from said second end of said base; said carriage includes: a first rail; a second rail disposed spaced and parallel to said first rail such that said rails are bearingly supported by said base of said frame for permitting sliding of said carriage relative to said base; said carriage includes: a first arm; a second arm disposed spaced and parallel relative to said first arm such that the spool extends between said arms; an axis of rotation of the drum is disposed parallel and spaced relative to a rotational axis of the spool; said axis of rotation of the drum is fixed while said rotational axis of the spool is movable so that a distance between said axes is controlled by said control device; said carriage includes: a drive drivably connected to the spool for rotating the spool and the reel supported thereon; said moving device includes: a hydraulic cylinder having a first and a second extremity, said first extremity of said hydraulic cylinder being connected to said carriage, said second extremity of said hydraulic cylinder being connected to said further stand, said hydraulic cylinder being connected to a source of pressurized hydraulic fluid; said reel in position control device is connected to said hydraulic cylinder for controllably moving said carriage; and said reel in position control device is controllably connected to said drive so that when said reel has been wound, said control device disconnects said drive from said spool.
