HORACE'Z. LANDON, OF NE'WTONVILLE, MASSACHUSETTS.
i CORE.
Application filed November To all whom 'it may concern.'
Be it known that I, HORACE Z. LANDON, a citizen of the United States, residing at Newtonville, in the county of Middlesexl are ultimately to form the central support for roils of narrow fabric, tape and the like.
The usual method of manufacturing narrow rolls of wound goods, such as friction tape for example, consists in winding or rolling a wide stri-p of the material on a long core and subsequently cutting transversely through the entire roll to form a number of narrow rolls of the desired trade widths. Because of its economy and simplicity, a rolled paper tube is ordinarily used for the core. However, it has been found that the cutting operation causes small particles to be torn or laked off from the main body of the core, these particles being impressed during the continuation of the cutting operation into the end surface of the roll of fabric. This not only forms an unsightly product due to the ragged edge exhibited by the core andthe presence of the Hakes in the ends of the roll, but also detracts from the eilicacy of the tape, because if the tape is of an adhesive nature the particles are retained thereon when it is unwound.
According to the present invention the long core before having the material rolled thereon, is dipped into or impregnated with an agent which will avoid objectionable ilaking of the core during the cutting operation. This agent may take a wide variety of forms, but it is preferred to employ something in the nature of a wax, which serves its purpose not only through uniting and forming a bond between individual fibres of the core, but also by providing lubrication for the knife or cutter. last feature Vis of importance because it makes for simple and economical cutting of the core, increases the life of the cutter and This S, 1923. Serial N0. 673,611.
enables more cuts to tool. Y
In the accompanying drawings Fig. 1 is a longitudinal section of a roll of material wound upon a long core showing one of the narrower rolls severed from the main roll; and Fig. '2 is an end elevation of one of the finished rolls.
The invention is `herein described as embodied in the manufacture of rolls of rubberized fabric or friction tape. Referring to Fig. 1, a central core 4, ordinarily about et) inches long, consists of a tightly wound roll of paper which may be wound in a parallel, spiral, or helical manner, as is well known. In order to prevent flaking of the core during the subsequent cutting operation, the core is then dipped in a hardening, stiifening or lubricating compound of a consistency to insure thorough impregnation of the compound Iinto the fibres of the paper. For this dip, it is preferred to use melted paraffin, which upon hardening, not only gives a solid homogeneous core, but also n provides an efficient lubrication for the cutting tool. After the removal of the core from the parain dip the core is allowed to cool to harden the parafn, and is then wound with the treated fabric 6 to form a roll of the desired diameter. The completed roll is then mounted on a mandrel and rotated at the proper speed, during which a cutter is pressed at successive points along the roll to cut the latter into a number of narrow finished rolls of tape, one of which is indicated at 8 in Fig. l. The type of roll obtained from existing methods when the core is not impregnated, is illustrated in side elevation in Fig. 2, the flakes torn from the core being impressed by the tight frictional engagement of the roll on the cutter into the ends of the roll, as indicated at pointsv 10. When the core is impregnated with the parain as above described, this objectionable iaking or breaking down of the core is avoided, because of the uniting of the fibres of the core, and also through the lubricating of the tool. Moreover, this action of bonding thefibres and layers of the core prevents the cutter from breaking down the inner wall of the core and leaving a loose flap when completed, as frequently occurs under existing methods.
be made by the same Having thus described the invention, What is claimed is:
l. A package comprising a roll of inaterial having a flat snri'ace capable of being marred during the process oie cutting said roll anda paper core, said core having been treated With an agent in such manner that iaking of the core is prevented When said package is cut to length.
2. A package comprising a roll of material having a flat surface capable of being marred during the process oi:l cutting said roll and a paper core, said core having been treated with an agent in such manner that iaking of the core is prevented When said core is cut to length.
3. A package comprising a roll of adhesive tape to Which flakes of paper would adhere and a paper core, said core having been treated with an agent in such manner that 'laking of the core is prevented when said package is cut to length.
f. A package comprising a roll of adhesive tape to Which flakes oi" paper would adhere and a paper core, said core having been treated With an agent in such manner that flaking of the core is prevented when said core is cut to length.
5. A package comprising a roll of adhesive tape to Which flakes or paper would adhere and a paper core, said core having been impregnated with paraffin, lin such manner that flaking of the core is prevented when said package is cut tolength.
6. A package comprising a roll of adhesive tape to which Hakes of paper would adhere and a paper core, .said core having been impregnated with paraiiin in such manner to render said core seliE lubricating, and laking oi" the core prevented when the core is cut to length.
7. The method of making a narrow roll comprising a core on which is Wound material to which flakes 'from the core would adhere, which consists in impregnating a core oi paper in such manner as to render said core non-liaking and self-lubricating, winding said material on the core and cutting both the core and the material into narrow Widths.
8. rlhe method oit making a narrow roll comprising a core on which is wound material to which Hakes from the core would adhere which consists in winding a web of paper into tubular form with a parallel winding, impregnating said web with parai'iin to render the same noirflaking and self-lubricating when the same is cut vlo length7 winding on said core a web; o'' said material and subsequently cutting the i'oil of n'iatei'ial into short lengths.
