982,797. Injection moulding footwear. H. LUDWIG, [trading as DEUTSCHE SPEZIALMASCHINEN CO. H. LUDWIG KOMM. - GES.]. May 7, 1962 [May 8, 1961], No. 17383/62. Heading B5A. [Also in Division B8] In an apparatus for injection moulding footwear a plurality of mould assemblies are fed sequentially to the injection unit by means of two parallel roller tracks having swingable end members to transfer the mould assemblies from one roller track to the other. The conveyer system consists of two parallel roller tracks with head-pieces 21, 28 at each end which are adapted to pivot and co-operate with either roller track. The head piece 21 is mounted on three arms 22, 23, 24 which are pivoted to the frame at 25, 26, 27. The other head piece is similarly mounted and the two head pieces are arranged so that they swing together when operated by a cylinder 36 and chain 40. Each head piece has attached to it a feed cylinder 41, 44 which operates a driving member 47, 48 for moving the mould assemblies in the direction of the arrows A and B. The part of the roller track opposite the injection unit is adapted to be moved transversely to the roller track on rails 51 (Fig. 5) by a toggle 54, 55 which is actuated by a cylinder 52 to bring a mould assembly into engagement with the injection unit.
