Method and apparatus for the manufacture of a thermoformable and heat-sealable container material.

摘要

CONTAINER IN MATERIAL SELLABLE HEAT AND thermoformable includes a hollow housing comprising a pair of valves (2) connected by heat sealing ALONG THE EDGE IN CORRESPONDENCE WITH A LONGITUDINAL PLANE ESSENTIALLY MEDIANO having at least an indentation ( 5) in its base in which LOCATED LOWER PART HORIZONTAL (4) heat seal (3). METHOD FOR PRODUCING CONTAINERS INCLUDES A pre-heat sealable material sheets HEAT AND thermoformable; A heat-seal EDGES OF CONTAINERS WITH A SIMULTANEOUS insufflation FLUID IN ORDER TO AVOID THE SEALING OF CENTRAL AREA OF INTENDED PLATES FOR THE FORMATION OF THE WALLS OF CONTAINERS, AND TRAINING SIMULTANEOUS THROUGH heat sealing A number of conduits (75, 75A) for forming the tire, cOMMUNICATING WITH EACH OTHER AND CONTAINERS; Thermoforming CONTAINERS THROUGH INSULFLACION said fluid Such channels TRAINERS THROUGH INJECTORS (74) located upstream of the heat-seal station. ADEQUATE PLANT FOR STARTING method includes, in succession, a station (56) for preheating BLADES (53), a station (51) WARMING THE CLOSURE OF THE EDGES OF CONTAINERS, a station (52) FORMING CONTAINERS iNJECTION FLUID, a mechanism (55) to advance the blades, at least one station (57, 60, 63) TO REMOVE THE CIRCUIT CONTAINERS, a conveyor (59) for transferring the containers, railway heat-seal (51) it comprising a pair of die halves HEATED. Each die has at least one IMPRESSION (65) corresponding to the shape of the container. TROQUEL said half have at least one longitudinal OUT SLOT (66) which makes for communication with joy, at least one impression. The edges of said at least one groove and said at least one print has heat sealing surfaces (67).
