A molding apparatus which is used in a continuous molding operation includes an endless looped track (3), track carriers (9) which are moved around the track to and from a product shaping mold region (5) and a transfer system (20) for replacement of mold block members (4) used in the apparatus. The transfer system (20), which operates without interrupting the molding operation includes transfer carriers (23) controlled to move synchronized with the track carriers (9) at a transfer location (20) remote from the mold region (5) and actuators (25, 27) which slide the mold block members (6, 4) between the track carriers (9) and the transfer carriers (23) at the transfer location (20) when the transfer carriers (23) are synchronized with the track carriers (9).
摘要:
The invention relates to a facility comprising moulds into each of which a latex foam is introduced and a furnace (1) into the vulcanizing chamber (1a) of which the moulds are introduced with a view to vulcanizing the latex foam for the formation of articles. The facility further comprises a mould filling station for filling the moulds with latex foam, a stripping station for removing the articles and a washing unit and drying unit for the stripped articles. The vulcanizing chamber (1a) is embodied by a shell (1b) arranged at a distance from the side walls and above the furnace, which together with the latter delimits an enclosed space (1c) which communicates with the vulcanizing chamber (1a) by way of passages embodied in the lower part. The invention provides for the upper part to have at least one opening for introducing steam which communicates with the enclosed space and for the lower part to have at least one opening for extracting the steam and evacuating the condensed water.

Eine Vorrichtung zur Herstellung von Rohren (15) aus thermoplastischem Kunststoff mit Querprofilierung weist auf einer Formstrecke (2) paarweise in Kreislauf geführte Formabschnitts-Hälften (4, 5) auf. Es ist eine Transportvorrichtung (29) zur Rückführung der Formabschnitts-Hälften (4, 5) vorgesehen, die nach Art eines Brückenkranes ausgebildet ist. Auf einer die Formstrecke (2) übergreifenden Transport-Brücke (34) sind zwei quer zur Produktionsrichtung und gegensinnig zueinander verfahrbare Transport-Wagen (44, 45) vorgesehen, an denen jeweils ein nach unten gerichteter Transportarm (53) mit einer Haltevorrichtung (54) für je eine Formabschnitts-Hälfte (4, 5) angebracht ist.
摘要:
A machine for the production of seating components having a plurality of movable press centers which are moved about by a track to a plurality of workstations where different manufacturing operations are performed. The track is equipped with transfer capability to selectively bypass one or more of the workstations to enable different components to be made simultaneously using different methods. The track can further move a press center off line for repair without interrupting the operation of the machine. Each centers comprising: a stationary press platen carrying a trim tool (24) for sharping said cover member; a movable press platen (28) having two sides with different tools (48,50) on each side for performing different manufacturing operations; means (46) for rotating said movable press platen (28) so one side or the other of said movable press platen faces said stationary press platen; and press means (34) for moving said movable press platen (28) toward said stationary press platen to move one of said tools to said trim tool for performing one of said manufacturing operations.
摘要:
Procédé de fabrication d'éléments (7) de coussins et de matelas réalisés en matière cellulaire souple à cellules ouvertes, par la coulée dans un moule (1), à partir d'une tête (19) assurant le mélange d'au moins deux composants de base, du produit (31) ainsi formé ; on transfère ledit moule depuis un poste (5) de préparation où on projette un agent démoulant, pour le présenter sous ladite tête (19); on déplace celle-ci suivant un tracé continu (33) couvrant au moins toute la surface du moule (1) et à une vitesse assurant, d'une part, une répartition uniforme du produit (31) et d'autre part, un temps total de parcours inférieur au temps d'expansion maximum du produit projeté en début de ce tracé; on ferme un couvercle (9) sur ledit moule (1), et on le transfère vers des postes d'attente (2, 3) où il demeure ainsi pendant un temps supérieur à celui de la maturation de la matière cellulaire obtenue; on enlève l'élément (7) de coussins ainsi constitué et on transfère à nouveau celui-ci vers le poste (5) de préparation.
