Definitions
- This invention relates to thermoplastic strip materials wound into a roll, and more particularly to means for the prevention ofthe premature unwinding ofsuch rolls.
- the invention features an article of manufacture comprising a roll of an elongated strip of material having thermoplastic surfaces wound in a multiplicity of convolutions, wherein a portion of the ultimate convolution is fused solely by strip thermoplastic substance to the penultimate convolution and to no other convolution to provide a breakable connection between those two convolutions, the maximum strength of the breakable connection being substantially less than the ulti mate tensile strength of the strip at the breakable connection.
- the portion of the ultimate convolution which is so fused is spaced from the free end of the strip of material so as to provide a finger tab which may be grasped when it is desired to break the breakable connection, such having a minimum strength capable of supporting the roll when supported by the tab.
- FIG. 1 is a perspective view of a roll of strip material according to the invention.
- FIG. 2 is a section taken at 2-2 of FIG. 1.
- FIG. I shown a strip of thermoplastic material wound into a roll 12 which comprises a multiplicity of convolutions.
- strip 12 is composed entirely of thermoplastic material. It will become apparent, however, that the invention extends to a laminated strip having surfaces of thermoplastic material.
- the ultimate convolution of roll 12 is fused, solely by the thermoplastic substance of the strip, as more fully described below, to the penultimate convolution in a line 14 which preferably extends across the entire width of the roll 12, providing a novel breakable connection only between those two convolutions.
- Such line of fusion 14 is spaced from the end 16 of the strip of thermoplastic material 12, thus provid ing a finger tab 18. This tab may be grasped by the user when it is desired to break the connection formed by fusion line 147
- a more detailed view of the fusion line 14 may be seen in FIG. 2.
- the breakable connection provided at the fusion line l4 break selectively when the tab 18 is pulled without damage to the strip of thermoplastic material itself beside the connection. Such damage would most likely take the form of a tearing of the strip in the region of the breakable connection between the ultimate and the penultimate convolutions. Too, it is desirable that the minimum strength of the breakable connection be such as to permit convenient handline of the roll, as by picking it up and so freely suspending it by finger tab 18.
- a heat source is applied to the region of the ultimate convolution where the fusion is desired.
- the strength of the breakable connection will depend upon various factors.
- thermoplastic material the temperature of the sealing device, the dwell time of the sealing device upon the thermoplastic material, and the pressure with which the device is used.
- Rolls of high-density polyethylene and urethane foam very advantageously employ such a breakable connection to prevent unraveling. It has been found essential, however, to employ a heat source which has a very accurate temperature control so that the operator can employ a single convenient dwell time and pressure, for any given thermoplastic material, which will provide a breakable connection of the type described above.
- a Teflon coated heat selling wheel sold by the US. Plastics Corporation of Lima, Ohio under the trade name Sealine Hand Sealer" has been found to be adequate for this purpose.
- An article of manufacture comprising a roll of an elongated strip at least the surfaces of which are thermoplastic material wound in a multiplicity of convolutions and having a portion of the ultimate convolution fused solely by said thermoplastic material to the penultimate convolution and to no other convolution, providing a breakable connection between said two convolutions spaced from the free end of said strip providing a finger tab, said breakable connection having a maximum strength substantially less than the ultimate tensile strength of said strip at said breakable connection for the destruction of said connection without tearing said strip for unwinding said multiplicity of convolutions.
- thermoplastic material is urethane foam.
- thermoplastic material is high-density polyethylene.
