Abstract
An apparatus and method for cutting a travelling paper web 20 winding on a spool 24 and transferring the web 20 onto an empty spool 27 by attaching a cutting tape to the empty spool 27, including a repulpable paper fiber stiff tape 30 passing through an elongated guideway 34 from near end 38 to far end 36; the apparatus and method characterized by: (1) adding adhesive to one surface of the tape 30; (2) gripping the tape 30 adjacent its leading end after it has exited from the guideway 34; and (3) releasing the tape 30 at a selected time and permitting the leading end 37 to move forward into contact with the nip 29 between empty spool 27 and driving roll 23.
Claims14
In a system for cutting with a tape a travelling web of paper being wound on a first spool and transferring that travelling web onto an empty spool by attaching said tape to said empty spool, said tape travelling slidingly through a guideway with an elongated slot facing upwardly underneath said web and exiting from said guideway beyond the edge of the web;
- the improvement which comprises clamping means for releasably gripping said tape adjacent the forward end thereof to prevent movement of the tape after said forward end has exited from said guideway and selectively releasing said tape to permit forward movement of said forward end into the nip between said empty spool and the cooperating roller driving said empty spool.
An improved method for cutting a travelling web of paper being wound on a spool and transferring the web after cutting to an empty spool, the method including a cutting tape being fed into an elongated guideway positioned beneath and extending laterally across the web of paper, recovering the tape from the far end of the guideway and introducing it into the nip of the empty spool and the roller driving that spool to cause the tape automatically to spirally wrap around the empty spool while cutting the web of paper;
- wherein the improvement comprises the steps of:
- (1) feeding said tape into a guideway;
- (2) receiving the tape leaving the far end of the guideway into a remotely controlled clamping means;
- (3) gripping the tape near its forward end by said clamping means with said forward end extending beyond said clamping means;
- and
- (4) releasing said clamping means and moving said forward end of said tape into contact with said nip.
