Abstract 1,138,527. Packaging in flexible tubes. COLODENSE Ltd. 5 Dec., 1966 [11 Dec., 1965], No. 52727/65. Heading B8C. [Also in Division F2] The guide 3 (Fig. 1) about which a web 16 is tubed with its edges overlapping, can be turned about a vertical axis to alter the position of the overlap in relation to the plane in which the tube is subsequently flattened by welding heads 14. A structure 5 rotating with the forming guide 3 about a bearing 6 also carries the web supply 17 and a glue-strip applicator 8, which may, however, be omitted where the longitudinal seal is to be made by a heat-sealing head 13. In the machine illustrated the tube is drawn downwardly by the welding heads 14 and is fed with sweets 26 through a feed tube 1. The sachets 27 may be closed by rupturable seals as in Specification 956,506, and a strip of tacky adhesive may be provided for resealing them.
AN APPARATUS FOR THE CONTINUOUS PRODUCTION OF SEALED FILLED ENVELOPES COMPRISING A DOWNWARDLY DIRECTED FILLER TUBE DOWN WHICH GOODS MAY BE FED, A FORMING MEMBER MOUNTED FOR ROTATION ABOUT THE FILLER TUBE FOR FORMING A TRAVELLING SHEET OF HEAT-SEALABLE WRAPPING MATERIAL INTO A TUBE HAVING OVERLAPPING EDGES ABOUT THE FILLER TUBE, A SUPPORT FOR A SUPPLY OF WRAPPING MATERIAL FIXED TO THE FORMING MEMBER AND MOUNTED FOR ANGULAR MOVEMENT WITH THE FORMING MEMBER ABOUT THE LONGITUDINAL AXIS OF THE FILLER TUBE, A SEALING MEANS FOR SEALING THE OVERLAPPING EDGES OF THE TUBE OF WRAPPING MATERIAL ALONG A LONGITUDINAL STRIP, ADVANCING MEANS FOR PROGRESSING SAID TUBE OF WRAPPING MATERIAL DOWNWARDS FROM THE FILLER TUBE, A PAIR OF HEAT-SEAL JAWS PLACED BENEATH THE FILLER TUBE TO BE RECIPROCABLE TOWARDS AND AWAY FROM THE FILLER TUBE AXIS FOR TRANSVERSELY SEALING TOGETHER OPPOSED WALLS OF THE TUBE OF WRAPPING MATERIAL AT ENVELOPE LENGTH INTERVALS AND A CUTTING MEANS PLACED BENEATH THE FILLER TUBE FOR SEPARATING INDIVIDUAL SEALED FILLED ENVELOPES FROM THE TUBE.
