Abstract: A rectangular tray-type carton formed from a blank of plastics-coated board has a peripheral flange for attachment of a closure lid. The flange is formed after the erection of the carton side wall in a punch and die arrangement, by folding down elongate panels carried along the free edges of the side wall and by subsequently joining the panels together at their ends by means of overlapping tabs which are heat-sealed together. In order to avoid damage to the tabs during formation of the side wall the uppermost tabs are folded out of the plane of the blank before it enters the punch and die arrangement.

Abstract: Circular chip control insert including a plurality of peripheral arcuate scallops having adjacent intersections terminating in points at the cutting edge of the insert providing a wedge effect in dividing and breaking chips.

Abstract: A pair of specially designed suction wheels are preferably placed after the glue applicator on a known pinch bottomer bag-making machine. During manufacture, paper bags are guided horizontally through the machine by a conveyor forming part of the machine. With this arrangement, one of the suction wheels is placed under the bag, and the other wheel is placed over the bag in line. As each bag is moved by the conveyor, both suction wheels are brought into motion like a rolling operation. Each wheel has a shaft with a hollow channel going to a suction cup at the periphery of the wheel. The number of suction cups around the circumference of the wheel could be any amount. In a preferred embodiment, there are 12 equally spaced suction cups. A vacuum pump with a hose is connected onto the shaft. The pump draws air through the channel which comes from a suction cup so that, when the bag comes into the vicinity of the suction cup, the cup sticks on the bag layer.

Abstract: A set-up method for unequal speed circumferential rolling. The setting values of the circumferential speeds of a higher speed roll and a lower speed roll and the roll position are obtained by using, as rolling parameters in a rolling schedule, the inlet and outlet thicknesses, the forward and backward tensions, the radii of the rolls, the frictional coefficients and the ratio of the circumferential speeds of the rolls. The setting values are computed such that these values meet the rolling conditions within both the load limit value and the tension limit value.

Abstract: Apparatus for assembling axially elongated, diametrically expandable and contractible product bags axially within energy sleeves of elastomeric material which are at least partially diametrically expanded at assembly. The apparatus comprises three, (3) energy sleeve expansion stations where at the elastomeric sleeve is sequentially expanded by the insertion of expansion rods and/or tubes therewithin. From the third station the energy sleeves proceed to an assembly station with an expansion tube therewithin. At the assembly station a product bag is inserted axially within the expansion tube in the energy sleeve with an end portion protruding from the tube. A first mechanism moves the energy sleeve axially relative to the tube so that an end portion surrounds and frictionally grips a part of the protruding product bag.

Abstract: Method and apparatus for controlling the spacing between a metal forming punch and a die pad in which the method includes supporting the work-piece on a fluid supported pad and the periphery of the work-piece on a fluid supported sleeve, engaging the workpiece with a forming punch and, during a portion of the travel of the forming punch, moving the pressure sleeve and the support pad for the central portion of the workpiece simultaneously while maintaining the spacing between the top of the pad and the bottom of the punch. The apparatus includes a die pad riser attached to the pad and to a pressure sleeve, both of which are movable in response to movement of the punch during a portion of the travel of the punch. The pressure sleeve is secured to the die pad riser so that the spacing between the punch and the die pad is maintained during such movement.

Abstract: Newspaper or the like is prepared for burning by folding and rolling operations to provide its complete combustion. The paper is folded such that one edge is placed parallel to and spaced from the opposite edge. The folded paper is then rolled to form a cylindrical fuel element. The cylindrical fuel element is advantageously placed in a fixture retaining its rolled and folded condition during binding. The fixture includes a first and second end supports forming a rectangular channel receiving the cylindrical fuel element. A connecting member maintains the supports relative to each other. A constricting member is positioned in the channel which reduces the width of the channel to maintain the fuel element in its rolled condition. The fuel elements may be in the form of kindling sticks, or bundles of such sticks, or individual logs.

Abstract: A process for casting molten metallic material having a solidification ra of temperatures, especially alloys containing more than 80% aluminium, involves simultaneously stirring and cooling the molten material to a temperature between 0.degree. C. and 75.degree. C. above the liquidus temperature of the metallic material using hollow heat transfer rods (9) extending across a duct (4), down which the material is caused to flow. The material is then caused to solidify with a substantially non-dendritic microstructure by rapidly cooling it in a continuous casting machine. The solidified bar so produced may then be reheated at a steady rate to a point between its liquidus and solidus temperature until it contains between 30% and 70% by volume solids content but can still be maneuvered without losing its shape. It may then, with a minimum of delay, be rapidly formed into a solid article of any desired shape by, for example, casting in a pressure casting machine.
