Abstract: The tap device 1 consists in an articulated mechanism 23 which positions each plastic bottle 5 against the corresponding spigot 2 in a tilted position. The aeration and foaming of the carbonated liquid beverage are thus decreased, filling is more stable, and the star-wheel for removal 3 may be provided with a capper 42 using screw-tops.

Abstract: Plastic bottle blanks (1) are rotated and conveyed neck down through a rotary thermal heating station (3), and neck up to a transfer station (5) and through a blow molding station (4), thus making it possible to simultaneously hold the blanks by their necks during the entire treatment and to easily remove the finished hollow bottles by gravity.

Abstract: This invention is addressed to a new and improved feeding device for feeding plastic materials, such as thermoplastic materials, to a processing machine including a fixed plate and a rotatable plate having an annular channel therebetween and a feed hopper to supply plastic material to the annular channel in which the feeding device comprises a metering screw to feed plastic material from the feed hopper to the annular channel and a hook-crown including a plurality of deflecting hooks mounted on the rotatable plate in the annular channel whereby the deflecting hooks sweep the volume of the annular channel and deflect the plastic material fed thereto by the metering screw to permit regular and efficient feeding to the processing device.
