Abstract
An apparatus 15 and method for cutting a travelling paper web 20 winding on a spool 21 and transferring web 20 onto an empty spool 23 by attaching a cutting tape to empty spool 23, characterized by: (1) a tape dispenser 16 supplying repulpable paper fiber stiff tape 24; (2) an elongated guideway 28 having an open end 49 through which tape 24 is fed to the opposite end 50, the ends being adjacent the side edges of web 20; (3) a cutter 38 to partially cut the tape 24 adjacent end 49; and (4) a friction brake 39 engaging tape 24 between the cutter 38 and end 49 to cause tape 24 to completely sever thereat as the tape is spirally wound about the empty spool.
Claims40
In an apparatus 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, the system characterized by:
- (1) means for supplying a length of repulpable paper fiber stiff tape;
- (2) an elongated guideway with an elongated open slot facing upwardly beneath said travelling web and having opposite open ends adjacent the side edges of said travelling web, said guideway receiving said tape delivered slidingly into one said open end and exiting out of the other said open end;
- and
- (3) a brake means frictionally engaging said tape.
An apparatus for cutting a travelling web of paper being wound into a spool and transferring the cut web to an empty spool for winding, said cutting and transferring being accomplished by attaching a tape to the edge of said empty spool, the apparatus being characterized by:
- (1) a continuous length of cutting tape wound on a rotatable drum, said tape being thin and stiff and comprising a plurality of lengthwise parallel strands of twisted repulpable paper fibers positioned side-by-side and bonded to each other by a water-soluble adhesive, said tape being one strand in thickness;
- (2) an elongated guideway slightly wider than the width of said tape, said guideway having an elongated slot on its upper side and closed on its lower side and having an inwardly directed shoulder, on said upper side along each lateral side of the guideway;
- said guideway being parallel to and extending substantially the entire length of said empty spool and being positioned below said travelling web of paper;
- (3) a brake means being located between said guideway and said drum, said brake means comprising an underneath supporting surface and an upper pressure surface adjustable to provide selective frictional resistance to the passage of said tape therebetween;
- and
- (4) cutting means for cutting laterally across said tape to partially sever said strands, said cutting means being located between said brake means and said drum of tape.
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 attachable to said empty spool, the tape automatically travelling spirally across said empty spool cutting the web of paper, and winding the cut portion onto the empty spool;
- wherein the improvement comprises the steps of:
- (1) feeding the free end of a stiff paper tape from the near end to the far end of an elongated guideway positioned beneath and extending substantially the width of said travelling web;
- (2) extending the free end of said tape from the far end of said guideway;
- (3) adhering said free end to said empty spool adjacent the far end thereof;
- and
- (4) applying frictional resistance to the removal of said tape from said guideway.
A 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 attaching one end of a cutting tape to the edge of the empty spool while applying tension to the other end of the tape stretched below the web and across the width of the web, the tape automatically travelling spirally across the empty spool, cutting and transferring the cut portion of the web to the empty spool, to be wound thereon, the method being characterized by the steps of:
- (1) applying an adhesive to the upper side adjacent the free end of a stiff paper tape;
- (2) feeding the free end through an elongated guideway extending at least from the near end to the far end of the empty spool and positioned below said travelling web, the guideway having an upwardly facing open slot over the entire length of the guideway to permit stripping of the tape there- through;
- (3) cutting partially through the tape laterally of its midsection adjacent the near end;
- (4) extending the free end of the tape from the far end of the guideway;
- (5) feeding the free end of the tape to the empty spool with said adhesive positioned to contact the empty spool;
- (6) applying tension to the tape in the guideway causing rupture of the uncut portion of the partially cut tape;
- and
- (7) automatically stripping the tape from the open side of the guideway as the web is cut and the cut web is transferred to the empty spool.
