Abstract
Equipment for the manufacture of hollow plastic bottles from preforms (16) having a closed end and an open end forming a neck, includes a conveyor equipped with supports (11) for the preforms which are driven in a predetermined path (T). The supports are arranged one after the other and are capable of pivoting over a given angular range when acted upon by a cam guide and follower arrangement (17, 18) such that the preforms may be inverted from their initial position. The cam guide may be an elongated, stationary rod (17) in the shape of a spiral section coiled around the path (T) followed by the swivel pins (13) of the supports, having a length determined according to the pitch of the spiral and to the angular swing amplitude required for the preforms. Follower rollers (18) are mounted on each support and flank the rod (17) such that, during the displacement of the supports along their path, the supports and preforms carried thereby are swung through 180.degree..
