MACHINES FOR THE PRODUCTION OF RECEPTACLES OF PLASTIC MATERIAL

PCT No. PCT/IB96/00702 Sec. 371 Date Dec. 31, 1997 Sec. 102(e) Date Dec. 31, 1997 PCT Filed Jul. 16, 1996 PCT Pub. No. WO97/03805 PCT Pub. Date Feb. 6, 1997The machine for the production of receptacles of plastic material includes a loading device (5) in which the preforms are disposed neck down on supports (7) of double carriers (8) heated in a heating device (10) and moved into a drawing-blowing device (12). In this latter, the receptacles are formed and then discharged into a discharging device (14). In the part (21) of the guide track (20) the supports (7) and the preforms are aligned in a single row, whilst in the part (22) the supports (7) and the preforms are arranged in a plurality of parallel rows. Between each row of preforms of a row of carriers (8), the heating device (10) includes a heating body (42) arranged so as to heat bidirectionally the preforms located on each side of the heating body (42). The heating device can moreover be raised from an active position to an inactive position and vice versa. There is thus obtained a machine with a very high output, of reduced size and low consumption of energy.
