Abstract

1339545 Machines for making seamed tubes from blanks; seaming KEYOLOK CO Inc 11 Dec 1970 [21 July 1970] 35370/70 Headings B5D and B5K [Also in Division B8] Apparatus for forming sealed tubes from scored cardboard blanks with a thermoplastics sheeting lamination secured by a heat-melting adhesive wax, comprises an endless chain conveyer 3 carrying clamps 2 by which separate blanks are transported from a magazine 1 (see Division B8), through successive work stations at one of which partial de-lamination of the blank is carried out. Each blank first passes through station 20, after opposed edges have been aligned by shoulders on clamp 2, and is folded by ploughs and a mandrel to the stage of Fig. 3E. The blank is then pre-heated at station 33 to melt the wax between the cardboard, and sheeting below fold-line a. A pressure-heater device 38, comprising opposed heated aluminium blocks 41 pivotally mounted in pairs on ceramic blocks 40 carried on an endless conveyer, then forms a weld seam along the adjacent longitudinal edges of the thermoplastics sheeting. A subsequent refrigerated member 45 sets the wax along one margin only of the blank, the melted wax elsewhere being absorbed by the cardboard to allow separation of cardboard and sheeting layers. Next, device 47 applies hot melted adhesive along a longitudinal flap and the blank then enters folding station 51 in which conveyer 52 co-operates with a front plate to form the blank into a tube, as in Fig. 4H, a wedge pressing the bottom wall somewhat outwards horizontally of a vertical side wall to start delamination of the blank layers. Station 51 also includes a knock-down device comprising a top wall 55 and a spring-loaded front wall 56 which pivot as a unit under the control of a follower in the cam track of a rotary cam. Compression belts 68, one being refrigerated, then set the adhesive on the flap to secure the tube into which the blank is then erected by plough 70. The blank is finally removed by discharge conveyer 71. The work-stations are adjustable by hand crank 31a to receive different sizes of blank.
