A system for preconditioning preforms prior to reheating the preforms for blow molding, includes an area for receiving finished preforms, a conveyor for moving the preforms from the area and to a blow molding operation, a reheat section connected with the conveyor for receiving the preforms and for heating the preforms in preparation for blow molding, and a preconditioning section for preconditioning the temperature of the preforms prior to distributing the preforms to the reheat section such that the heat energy contained by each preform is substantially the same and uniformly distributed throughout each preform.

Preconditioning preforms on a reheat blow molding system

An inventive orientation apparatus is provided in the present invention preferably for use with blow molding operations. The apparatus includes an object having a body portion and a neck portion. The neck portion has an outer peripheral surface and an alignment lug which extends outwardly from the peripheral surface and past the same. Additionally, a rotating support is included for supporting the object and causing the same to rotate, wherein the rotating support is movable with a moving carrier pallet. The apparatus also includes an orientating element located adjacent the carrier which engages the alignment lug on the object and stops the rotation of the object at a desired orientation. The invention may also include an orientation check device which is positioned upstream from the orientation element, adjacent the carrier, which is used for checking the orientation of the alignment lug for preventing a system jam.

Preform orientation apparatus

Apparatus for forming hollow plastics including reciprocable mold portions to form a blow mold movable from an open position to a closed position a holding device for holding the parison within the blow mold. An alignment device is provided for aligning the parison with the blow mold.

Apparatus for preparing hollow plastic article

Apparatus for the manufacture of blinds of the type having a head rail, a plurality of ladder tapes, plurality of blind slats, and raise cords passing through the blind slats, by which the blind slats may be drawn upwardly toward the head rail, and wherein the apparatus has a die support for passage of strip material along an axis therealong for the formation of blind slats, a plurality of die units mounted on the die support, at least some of said die units being moveable therealong, the die units being aligned with one another along the strip path, the die units being operable to procure their selective operation to form openings in the strip material at pre-selected spaced points, a cut off die for cutting off a pre-selected length of the strip material to form a blind slat, and slat threaders located downstream of the dies for threading a slat through the ladder tapes. Also disclosed is threader apparatus which is moveable laterally relative to the axis of the strip material.

Apparatus for the manufacture of blinds

Apparatus includes a blow mold for forming a hollow plastic article forming a parison including at least reciprocable mold portions affixed to platens, wherein the mold portions are relatively movable from an open to a closed position including a spacing bar contacting the platens in the mold closed position operative to space apart the mold portions in the closed position thereof to form a controlled vent therebetween.
