DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an apparatus and method for cutting a travelling web of paper being wound on one spool and transferring the web to an empty spool while the web is travelling.
BACKGROUD ART
It is a general practice in the paper industry to produce a continuous sheet or web of paper which is wound onto large spools. In order to have a continuous operation it is, of course, necessary to have a system for instantaneously switching from winding the web of paper onto a full roll to an empty roll, particularly at modern speeds of paper production. In U.S. Pat. No. 2,461,246 there is shown a method of feeding a tape onto the rotating empty roll core and causing it to be spirally wrapped on that core as it stretches tight across the travelling web of paper and cuts the paper, with the cut edge being led onto the empty roll supported by the cutting tape. Subsequent improvements have dealt with methods of stringing the tape for cutting and feeding, and the use of various types of tapes, as shown for example in U.S. Pat. No. 3,599,888. A more recent improvement is found in U.S. Pat. No. 4,414,258 where there is described a tape made of repulpable paper woven into a tape which did not interfere with the paper making process since the paper wound adjacent the roll is waste and is recycled.
It is an object of this invention to provide an improved apparatus for cutting a paper web and transferring the cut portion to an empty spool. It is another object to provide such a system employing an improved repulpable paper tape. Still another object is to provide a substantially automatic feeding apparatus for introducing the tape to the empty spool. Other objects will appear from the more detailed description which follows.
BRIEF DESCRIPTION OF THE INVENTION
This invention relates to an apparatus for cutting a travelling web of paper being wound on a first spool and transferring that travelling web onto an empty spool by attaching a cutting tape to the empty spool, the apparatus 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, the guideway receiving the tape delivered slidingly into one open end and exiting out of the other open end; and
(3) a brake means frictionally engaging the tape.
The apparatus also includes a dispenser having a continuous length of cutting tape wound on a rotatable drum and being thin and stiff and being formed of a plurality of lengthwise parallel strands of twisted repulpable paper fibers laid side-by-side and bonded to each other by a water-soluble adhesive and being one strand in thickness. A cutter is provided between the brake means and the drum for cutting laterally across the tape to partially sever the strands. The brake means is located between the guideway and drum and includes an underneath supporting surface and an upper pressure surface adjustable to provide selective frictional resistance to the passage of the tape therebetween. The tape completely severs upon the passage of the partially severed strands between the brake means and the ends of the guideway as the tape is being spirally wound about the empty spool.
This invention also relates to 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 the empty spool, the tape automatically being wound spirally about the empty spool and cutting the web of paper, and winding the cut portion of the paper web onto the empty spool; the improvement comprises:
(1) feeding the free end of a stiff paper tape into the near end of an elongated guideway beneath the travelling web and extending beyond both ends of the empty spool;
(2) extending the free end of the tape from the far end of the guideway;
(3) adhering the free end to the edge of the empty spool;
(4) partially cutting
