摘要： Thermoforming machines with a heating station and a downstream mold station have carrier clamp frames for gripping the edges of sheets of plastic at a load station and indexing them successively to a heating station and a mold station. The carrier frame members to which the plastic may be releasably clamped carry their own remotely operated clamps and are themselves expandable and contractible to a condition in which, prior to molding, they control the sag in the sheet formed during heating of the sheets to differential pressure forming temperature. The plastic sheet can be molded to only a portion of a product which functions as a mold member.

摘要： A differential pressure forming machine with upper and lower mold members for forming cup-like articles in a web of thermoplastic material includes a mold assembly in which two separable die members, when in their closed position cooperatively form an article defining mold cavity which extends through one member and into the other. The two die members, when opened, are spaced from each other by a distance greater than the depth of the formed article. An endless chain of carrier members is located with one run extending between the two die members. Each carrier member has an opening smaller than the circumference of the formed article. Closing of the die members expands the carrier member opening outwardly of the periphery of the die cavity and closing of the entire mold assembly in the forming operation effects a severing of the formed article from the web. Upon subsequent opening of the die, the carrier member opening contracts, gripping the formed article to convey it clear of the mold as the next carrier member in the chain is advanced with the web into operative relationship with the mold. At a collection station a discharge member operative with the plug assist of the forming machine removes the formed and separated article from the carrier member.

摘要： L'actionnement d'un ajutage utilise pour la propulsion du fil dans un systeme de tissage d'introduction par air d'une trame est commande a l'aide d'une seule servo-vanne rotative (31) ayant un ensemble d'orifices (95, 103, 105, 107) adaptes pour coincider alternativement pendant la rotation de la vanne avec une source d'air sous pression et avec l'atmosphere pour pressuriser et mettre a l'event alternativement une chambre pilote (170) pour l'ouverture et la fermeture de l'ajutage. De preference, la vanne rotative (31) comprend un tiroir rotatif (75) entoure d'une manche en materiau permeable a l'air pour former un palier pneumatique pour le tiroir. L'actionnement de l'ajutage est determine par le mouvement d'une vanne a diaphragme (80) vers et en retrait de l'ouverture d'une chambre d'alimentation de l'ajutage (156) sous la commande de la pression de la chambre pilote, et le diaphragme est deforme en deux circonvolutions en U separees annulairement (212, 214) s'ouvrant vers l'interieur de la chambre d'alimentation en air de l'ajutage de sorte que le mouvement du diaphragme pendant l'ouverture et la fermeture suive une action de 'roulement' ou de flexion progressive au fur et a mesure que les parois laterales des circonvolutions se deplacent vers l'exterieur et vers l'interieur de maniere telescopique l'une par rapport a l'autre. De preference, deux diaphragmes en circonvolutions sensiblement identiques (180, 210) sont disposes espaces axialement et directement opposes l'un etant expose a la pression d'alimentation de l'ajutage et l'autre a l'impression de la chambre pilote. D'une maniere avantageuse, l'espace interieur entre ces diaphragmes est mis a l'atmosphere (224) pour maintenir dans cet espace des conditions sans pression et des espaces de degagement sont prevus pour empecher l'emprisonnement d'air resistant a la deflexion de l'un ou l'autre des diaphragmes.

摘要： Stacks of generally dish-shaped, nested plastic articles are gripped and transferred from elevated, horizontally ad- jacentchutes comprising circumferentially disposed, axially extending supports, which are open at both ends to permit articles to be both fed thereto and removed axially therefrom, to a conveyor disposed at a lower level. A transfer arm, mounting stack gripping receivers, which pivot on the transfer arm, is swung in an arcuate path and the receivers are moved relative to the transfer arm, responsive to swinging movement of the transfer arm, such that the receivers travel from a first position, horizontally axially aligned with said chutes and axially intermeshed with the supports, in a path having a first axially linear increment, then a downward arc to rotate said stacks substantially 90°, and finally a vertically linear path to deposit the stacks on the conveyor. The receivers are radially contracted to peripherally grip stacks of articles in the chutes when the receivers are in the first position, and are radially expanded to peripherally release the stacks when the receivers have moved the stacks to the conveyor.

摘要： A trim press is provided with a remotely controlled adjustment by means of which the end limit of the feeding stroke of the feeding mechanism may be precisely adjusted relative to the die of the trim press while the machine is in operation. Oscillating and reciprocating members of the prior art trim presses are replaced by continously rotating members to enable a higher rate of operation.
