Title: Mfg. hollow shapes from thermoplastics - involves continuous extrusion into heat insulated chamber for uniform temp., reduced heat loss and parison sag, before transferring to blowing mould
Inventor: KIEFER ERICH DIPL ING
IPC: B29C49/42
Filed: 1991-07-04
Abstract: Hollow shapes in thermoplastics are mfd. by extrusion blow moulding. During continuous extrusion of the parison, this is held in a thermally-insulated chamber, before transferring to the blowing mould. Several parisons may be extruded simultaneously into a common insulated chamber, with separate blowing moulds. Alternatively, two or more blowing moulds may operate with a single extrusion head and common insulated chamber. When the parison has extruded to the required length and the chamber and mould open, either the mould may move into position to close round and remove the parison, or it may be separately transported, e.g. by a gripper to the stationary mould, which may be alongside or beneath the insulated chamber. The blowing mould and chamber may be moved and/or opened/closed synchronously or independently. USE/ADVANTAGE - For continuously extruded blow mouldings, esp. those which because of weight or size would otherwise be intermittently extruded. Permits continuous extrusion for improved extruder operation and reduced complexity and cost of arrangement, esp. for greater product range. Reduces or avoids heat loss, giving more uniform parison temp. for improved product uniformity. Parison temp. at start of blowing is independent of time between start of extrusion and mould closing. Reduced heat loss permits lower extrusion temp., at or near blowing temp., reducing parison sag, and undesirable variations to product thicknes

IPC: A63B51/14
Filed: 1992-01-17
Abstract: A process is disclosed for determining tensile forces when stringing rackets with a bed of strings composed of parallel longitudinal strings and parallel transverse strings. The tensile force KPL for the longitudinal strings KPL is determined as a function of the length LL of the longest longitudinal side between the head of the racket and the heart of the frame in the bed of strings and the tensile force KPQ of the transversal strings is determined as a function of the length of the longest transversal string LQ in the bed of strings, of the length of the longest longitudinal side LL and of tensile force KPL. The tensile force KPL is multiplied by factors for the number of longitudinal strings SZL, the tension level SN, the type of impact ST and the frame hardness RH. The tensile force KPQ is multiplied by factors for the number of transversal strings SZQ and the type of impact ST. The factors are stored and may be selected by the user. The device for determining the traction forces when stringing rackets has a display unit, a microprocessor and a keyboard with keys for directly selecting the factors for the number of longitudinal strings SZL, the number of transversal strings SZQ, the tension level SN, the type of impact ST and/or the frame hardness RH, and for inputting the values of LL, LQ, SZL and SZQ.
