Abstract
554,346. Stamping plastic sheet material. BRITISH TYRE & RUBBER CO., Ltd., and EVANS, W. N. Dec. 26, 1941, No. 16693. Divided out of 550,014, [Group XVI]. [Class 87 (ii)] [Also in Groups XXII, XVI and XXIII] In a method of stamping plastic sheet material in which the sheet is placed between a die and an inflatable rubber bolster, the edges of the sheet are gripped between the margin of the die and the face of the bolster so that when the part of the bolster that engages the edges of the sheet is passed into engagement with a supporting surface behind it, and inflation commences to effect the drawing, the stretching of the bolster gradually releases the sheet as drawing takes place. The bolster 24, Fig. 3, is made with a flange 26 to which is vulcanized a backing sheet 27. Metal inserts 29 moulded in the rubber are tapped for fixing screws 31 for securing the bolster to the backing plate 20. A renewable wearing surface 28 may be vulcanized &c. to the front face of the bolster. The assembly is held by screws 23 in a flanged platen 21. In operation a spring pressure ring confines the bolster in its platen and fluid under pressure is admitted by a series of pipes and connections 35 to the interior of the bolster, forcing the. sheet material 39., 40 into dies 37, 38, parts of the front of the bolster coming into sealing contact with the back as shown. In another modification the bolster is constructed so that at all times pressure fluid has access to the whole of the interior. The fluid may be heated. Specifications 21287/00, [Class 87], and 21359/00, [Class 83], are referred to.
