Description

(54) IMPROVEMENTS IN OR RELATING TO PROCESSES USING HEAT SEALABLE MATERIALS FOR PRODUCING DESIGNS, PATTERNS OR CHARACTERS APPLIED TO A BASE SHEET (71) We, Cox & WRIGHT LIMITED, a British Company of P.O. Box 27, Wellingborough Road, Rushden, Northamptonshire NNl0 9BD, England, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to the production, from heat-sealable materials, of work comprising a base sheet of one material carrying characters or a pattern or design of another material heat-sealed on to the base sheet.
In a process for producing such work known as the tear-seal method, a sheet of applied material from which a design or pattern or characters are to be formed is placed in contiguity with a sheet of base material and the two are heat-sealed together by high frequency welding technique using a die that has a welding electrode that follows the outline shape of the design, or the like, that is required. After this heat-sealing step, an operator tears away the skeleton of the applied material sheet leaving behind the design. That is to say, when the operator rips off the applied material sheet it tears around the welded seams and the design remains. This process is called "applique welding", There are a number of problems with this tear-seal process.In the case where the applied design contains closed alphabetical letters, such as e's or o's or similar closed characters, the centres of these letters remain behind after the applied material skeleton is torn away and these have to be laboriously picked out by hand. Also, there is a risk that the operation may result in part of the design being torn so that a workpiece is wasted. The process becomes particularly difficult to carry out entirely satisfactorily when the base material is comparatively soft and the applied material forming the design is comparatively hard.
It is therefore an object of this invention to achieve an improved process.
According to the present invention, there is provided a process for the production, from heat-sealable materials, of work comprising a base sheet of a first sheet material carrying characters or a pattern or design of a second sheet material heat-sealed on to the base sheet, wherein, as a first step, the design is precut in but is not removed from a sheet of said second sheet material; as a second step, a base sheet of said first sheet material is laid up in face to face contiguity with the precut sheet; as a third step the precut design is heatsealed to the base sheet; and as a fourth step, the skeleton of the precut sheet around the design is separated from the design by being lifted or allowed to fall away. The skeleton of the sheet from which the design is cut does not, therefore, have to be torn from the base material.The precutting operation involves the use of a steel die with a cutting edge whereas in the heat-sealing operation a brass die has normally been used incorporating a raised edge to thin the applied material.
In one manner of carrying the invention into effect, described by way of example, a four-station rotary press table is employed, as shown schematically in the accompanying drawing. The four stations 1, 2, 3, 4 are disposed at 90" intervals around the table and there are press heads at two diametricallyopposed stations 2, 4. As the table rotates stepwise, an operator places a sheet of the material from which the design, pattern or characters are to be formed on the table at station 1, this material is precut at station 2, a second operator lays up a sheet of base material on the precut design material sheet at station 3 and the heat-sealing operation takes place at station 4. Unloading of the finished work is performed by the first operator at station 1 before the next sheet of design material is loaded.
The cycle time or rate of stepwise rotation of the table is governed by the welding time during the heat-sealing operation at station 4.
