Title: Apparatus for shaping an extruded article
Inventor: BULGIN DOUGLAS
IPC: F15B21/00
Filed: 1955-07-05
Abstract: 823,768. Shaping extruded articles. DUNLOP RUBBER CO. Ltd. June 28, 1956 [July 5, 1955], No. 19339/55. Class 87(2). Apparatus for shaping an extruded article comprises feeler means adapted to engage the article as it is extruded and to be actuated by it according to its profile, and a shaping device operated by the feeler means adapted to act upon the article to a degree dependent on the actuation of the feeler means. The invention is described in connection with the extrusion of a soft plastic rubber article having a circular cross-section and the compression of the article to an elliptical cross-section 1, Fig. 2. The compression is effected by two rollers 2, 3, the position of the upper roller being controlled by a spring which raises it and a compressed air supply 13 which depresses it through the medium of a diaphragm 14 and head 12. From the rollers the elliptical article is taken by a conveyer 5, Fig. 1, to a measuring device 6. This device, Fig. 3, comprises two rollers 22, 23. The upper roller 23 is carried by an arm 19 fulcrummed at one end between two springs 17, 18. The arm is counterweighted at 25 so that the roller 23 rests lightly on the article 1. At its other end the arm carries a vane 20 (see also Fig. 4) disposed between two jets 21. Compressed air passes through pipe 26, jets 21, pipe 28, capillary tube 30, chamber 31 and pipe 32 and pipe 13. As the article passes from rollers 2, 3 to measuring device 6 it swells. If it swells too much the roller 23, arm 19 and vane 20 are raised. Rising of vane 20 increases the air pressure passing through left-hand jet 21 and so depresses roller 3 to give an increased flattening effect on article 1. If the article has now swelled enough by the time it reaches roller 23 the vane falls and roller 3 rises.
