Abstract:
It comprises means (2) for advancing the bottles (3) and a cutting device (1) of the neck of the bottles. Said cutting device (1) comprises a pair of blades (7), a pair of rotating plates (4) for drawing the bottles (3) along and a plurality of drive pulleys (9) in contact with the bottles (3), in such a way that as the rotating plates (4) move so too do the bottles, at the same time rotating about their axes and in contact with the blades. These characteristics ensure fast and effective cutting of the bottles, while the cutting device occupies little space.

Abstract:
A blow pin assembly is provided for inflating a parison and forming the neck portion of a plastic container in a blow molding apparatus. The blow pin assembly is mountable to a blow rod. It includes a blow pin body including an exterior surface having a tapered portion and a cutting edge beneath the tapered portion. The tapered portion cooperates with the master seal of the mold to automatically center the assembly before the cutting edge engages the shear steels to sever the blow molded article from the mold. The cutting edge adjoins a rim extending substantially perpendicularly from the blow pin body, and can be resharpened one or more times.
Abstract:
The present invention includes a trim station for trimming the flange of a container, an apparatus for trimming the flange of a container and a method of trimming the flange of a container. The trim station includes a rotating primary knife and a secondary knife mounted on a movable member, wherein the secondary knife is moved into a cutting position by advancing the movable member in a direction parallel to the axial direction of the container. The present invention also includes a spindle assembly and a container by process of trimming the flange of the container.
Abstract:
The present invention includes an apparatus and method for trimming the dome of a container comprising at least one trimming station having a plurality of guide rollers and a knife, and a rotation guide. The apparatus is adapted so that the container is in contact with the rotation guide and at least two of the guide rollers during trimming.

Abstract:
A method of forming a wide mouth blow molded thermoplastic container comprising the steps of i) stretch blow molding from a preform, an intermediate article defining the container with the mouth being threaded and/or flanged, the mouth terminating in an accommodation element having a neck finish that supports the preform in the blow mold; ii) heat setting the intermediate article including the entire container while still in the mold, and iii) removing the intermediate article of manufacture from the mold and severing the accommodation element to produce the container, and an article when made by the method. The method also includes post forming of a rim portion of the container following separation of the container from the accommodation element.

Abstract:
A multi-station rotary blow molding machine having a plurality of separable blow molds angularly arranged in a serial fashion in a circular array within the machine. Each mold is comprised of two mold sections mounted for simultaneous movement toward and away from one another in a direction generally parallel to the rotational axis of the machine. An air supply manifold is provided for supplying air for both blowing articles and controlling certain portions of the molding machine for predetermined portions of a revolution of the molding machine. The mold sections are cooled in groups, each of the sections having an internal fluid path with adjacent mold sections being interconnected so that cooling fluid is passed serially between adjacent mold sections of each group.
