Abstract
664,010. Moulding tiles &c. ATLAS PRODUCTS (OVERSEAS), Ltd. Sept. 19, 1949 [Sept. 29, 1948], No. 24044/49. Class 87(ii) A web 5 of cementitious material carried by travelling moulds 1 is cut into tile lengths by a knife 6 which moves along with the web as it moves down to cut it. After cutting, the knife is moved up and to the rear, to displace the material of the new leading edge of the web, to form the head check of the tile. The knife is then held stationary, relatively to the web, while a plunger 9 presses the displaced material to the desired shape, Fig. 6, between the knife and a bar 8 having a profile to fit the contour of the top surface of the web. The depth of the cut and consequently the amount of material displaced may be adjusted by a stop 34, Fig. 2. The moulds are carried on supports 2 mounted in an endless conveyer 3. The supports have projections, Fig. 8 (not shown), which engage pivoted triggers in a slide 21, to move the slide along with the web. The slide has an outer cradle 18 with rollers 19 engaging with fixed rails 20. The cradle moves with the slide by means of connecting links 21a. The cradle 18 has rods 17 on which slides an inner cradle 16. The knife is mounted on a bracket 14 connected by arms 15 to the cradle 16. As the slide 21 is moved to the left by the supports 2, a latch 7 is released by a striker 7a to allow the knife to be moved backwards, when a roller 25, Fig. 2, hits an abutment 26 causing toggle arms 24 to be straightened and thus pushing the cradle 16 along the rods 17. Simultaneously a roller 27 engages a ramp 28 thus causing the arm 15 to lift the knife flush with the top of the web. A roller 11a then engages a ramp 13 to cause the plunger to be forced down against a spring 9a. The rollers 19 then engage a ramp 20a to lift the bar 8 and the knife. A cut-away part 28a of the ramp 28 allows the knife to remain stationary relatively to the cradles- A similar ramp 13a allows the plunger 9' to rise under spring pressure. To smooth the upper surfaces of the material the plunger is simultaneously given a lateral movement by moving a shaft 11 axially. The plunger may similarly be given a lateral reciprocating movement before it is lifted. A ramp 28b then gives the knife a final lift to allow the latch 7 to be reengaged. The hinged triggers on the slide 21 are now disengaged from the projections on the mould supports by coming into contact with fixed wedges. The slide 21 is: returned to its original position by levers which are moved by projections on the mould supports and which are automatically disengaged when the slide reaches its original position. The cradle 16 is returned to its original position by a lever 32, Fig. 2. To prevent the bar 8 from spoiling the surface of the web on its return journey, auxiliary rollers 30 and corresponding rails 31 are provided to lift the right-hand end of the cradle 18. Australian Specification 105,651 is referred to.
