Apparatus for producing hollow plastic articles in a hollow die with a relatively smaller reciprocating punch therein. Plastic material is fed from a nozzle aligned with the die, into the die about the punch, the punch being initially advanced into the opening of the die and retracting as the plastic is introduced from the nozzle. When the plastic introduction is completed, then the nozzle is slid laterally on the die until the duct of the nozzle is out of registry with the die and the nozzle thus closes the die. Then the punch is advanced within the closed die to compress the plastic material into the space between the die and the punch.

Apparatus for manufacturing an object in plastics material

The present invention is concerning a manufacturing process of an object made of plastic material in a mould comprising especially a die and a punch, this process being particularly interesting in that the obtained preforms may be formed by every known method, including thermoforming, blowing, etc. The process according to the invention is characterized in that a quantity of plastics material is introduced into the cavity of the mould, in that the flow of the material is controlled while it is being introduced into the mould cavity, by displacing at least part of the punch relatively to the die, in that the punch is subjected to a restraining action while the material is being introduced, and in that the cavity is closed and the plastics material contained therein is then compressed by displacing at least part of the punch in relation to the die.

Method of manufacturing an object in plastics material and object

Apparatus for connecting the leg of a skier to a ski comprises a casing comprised of rigid sections articulatedly interconnected for vertical swinging movement relative to each other about horizontal axes perpendicular to the length of the ski. In a preferred form, four such elements are provided, one comprising a sole or base, another comprising an upper pivotally mounted to the front of the base, and the third and fourth forming the front and rear of a boot top, at least one of which is pivoted to the rear of the base, the other being pivoted also to the rear of the base or to the rear of the upper. The various elements can be latched together in closed relationship; and means are provided for deliberately unlatching the elements to free the skier's foot, or for automatically unlatching the elements upon excessive forward or rearward bending or force application, or excessive torsional force. A waterproof sock can be provided within the casing.
