Abstract:
Un método y un aparato para formar una cadena (136) de resortes (16) encerrado dentro de bolsas individuales de un manguito de tela (33) que tiene faldones laterales superpuestos, planos (A, B). Los faldones forman una costura lateral que se extiende logitudinalmente (138) en la cadena, previniendo de este modo el problema comun del falso esponjado en las constucciones de colchon convencionales.
Abstract:
A method and an apparatus for loading articles into cases utilize indexed rotary movement of a carousel device (11) having a series of spaced apart platforms (12) with a case holding device (22) directly above each platform. Articles (17) are pushed onto one of the platforms at an infeed station, in a desired configuration for packing, with an open-bottomed case (21) held directly above the platform. The platform and empty case are then rotated to an offloading station, and the platform is raised up into the bottom of the case by camming action, in response to the rotation. At the offloading station, flap folders (51) push first and second bottom flaps of the case up into a closed position, and the case is pushed off the platform onto a conveyor, which also effects closure of a third flap up against the first and second flaps. There may be three stations, and the cases may be drawn from a flattened, stored configuration, opened and gripped by the case holding device at a station following the offloading station.
Abstract:
Flat, previously folded blanks are individually and cyclically conveyed by a rotor (1) to at least one gluing station (7), one assembly station (8) and one transfer station (10). The individual blanks are assembled into a box in the assembly station. The assembled boxes are kept in a stabilised state from the assembly station to the transfer station, over a path (9) that is sufficiently long for the glue to set. At the transfer station (10), the boxes are transferred to a second conveyor (12) that conveys them to a filling station (13). The rotary, cyclic processing of the individual blanks allows high processing rates to be achieved, in spite of a predetermined setting time for the glue that must to be respected.
Abstract:
A method for producing and filling a packaging for at least one article, in particular for displaying same. The packaging includes a generally planar support (2) on a receiving one (4) of the surfaces (4, 5) of which is mounted an article (3) held by holders (6, 7) such that part of the article may be seen and touched. The method comprises: providing a blank; placing the front flap (9) over a die (50) having at least one recess (51); applying a punch (53) to the accessible surface (52) of the front flap; grasping at least the front abutments (16, 16a); removing the punch; inserting the article into the resulting recess perpendicularly to the accessible surface (52); and at least indirectly feeding the die, the flaps and the articles to a sealing station (56).
Abstract:
The invention provides a machine and method for erecting, from a collapsed condition to an erected condition, a carton having a tray-like configuration. The machine comprises means for withdrawing a collapsed carton from a supply, means for moving apart top and bottom wall panels of the carton to bring the carton into a tubular configuration, means for causing a first end closure panel at each end of the tubular structure to be brought into a position to close the ends of the tubular structure, means for causing a second end closure panel at each end of the tubular structure to be brought into overlapping relationship with respect to said first end closure panels, and means for causing portions of said second end closure panels to be inserted into openings provided in one of the top or bottom wall panels of the carton to maintain the carton in its erected condition.
