Abstract

579,147. Sealing packages; making paper &c. bags. IDEAL PACKAGINGS, Ltd., and RAILTON, D. E. Feb. 24, 1945, No. 4701. [Classes 94 (i) and 94 (ii)] A heat-sealing machine which is used for closing the open ends of a tubular container, or for sealing material to form a bag having one or more compartments, is constructed with a pair of relatively movable jaws 1, 3 at least one of which is heated, the jaws being brought together by the action of an electro-magnet 7. The magnet 7 is controlled by a timing switch, and its armature 9 is connected by a link 24 to a bar 6 connected to tubular rods 5 which are depressed against the action of adjustable springs 18 to bring the upper jaw 3 into contact with the lower jaw 1. The link 24 passes through a central aperture in the bar 6 and transmits motion thereto via a nut 25 and washers 26. The jaw is adjustably secured to a heated casing 13 mounted on a table 2, and the jaw 3 to a casing 14 secured to a bar 4 mounted on the rods 5. which are guided by bushes 12 secured to the table 2. The magnet 7 is arranged in a casing secured to the table 2, and heating elements 10, 11 for the casings 13, 14 are controlled by thermostats. 'The springs 18 engage adjustable plugs 19, and plugs 20 which engage fixed pins 16 passed through the bushes 12 and through slots 17 in the rods 5. One timing switch can control a number of machines, and one thermostat also. The approach to the jaws may be controlled by a guard, and a stop may control the position of the container &c. before the jaws close on it.
