Abstract
693,647. Presses. HAGEN, R. Feb. 21, 1951 [Feb. 24, 1950], No. 4248/51. Class 140. [Also in Group V] A sheet 16, of thermoplastic material is placed on an endless metal band 10 and the band is then moved to the right to place the sheet in position 16a between two hot platens 4, 7. Platen 4 is mounted, together with a cooled platen 5, on a lower crosshead 3, and platen 7 is mounted, together with a cooled platen 8, on a fixed upper crosshead 1a. Another endless metal band 14 covers platens 7, 8. Crosshead 3 is then raised by hydraulic cylinder 2 to press the sheet, between the bands, against platen 7. Crosshead 3 is then lowered and the bands move to the right to place the sheet in position 16b between the two cooled platens 5, 8 ; at the same time another sheet is carried from the left into position 16a. Crosshead 3 is again raised, the first sheet being cooled under pressure and the second sheet heated under pressure. The crosshead is again lowered, and the first sheet is delivered to position 16c. Thus at each pressing operation one sheet is heated under pressure and another sheet is cooled under pressure. Insulation 6, 9 separates the hot and cooled platens. Instead of a single press, as shown, there may be two presses, one hot and one cold. Instead of endless metal bands, loose thin metal sheets may be used. Instead of two temperature zones, as shown; there may be three, there being an intermediate zone between the heating and cooling zones.. Continuous sheets may be produced by overlapping adjacent sheets in the press. Compound sheets may be produced by pressing leather or artificial leather sheets with thermoplastic sheets.
