A system and process for fabricating pressboard from shredded paper coated with a thermoplastic material and a pair of facing webs includes placing the shredded poly-coated paper between the two traveling webs to form a composite, the composite then being passed in a manner to heat the thermoplastic material above its softening point to differentially repeatedly shift the traveling webs linearly relative to each other and to the shredded paper for enhanced bonding of the shreds to themselves and to the facing webs by passing them around a series of heated rollers defining a serpentine path, and then pressing the composite together while curing to bond the components, and cooling the product.

A cam operated gripper driven by an endless chain receives at a feed station a wrapped straw having a heat-bondable portion and carries the straw to a bonding section. The gripper is associated with an electric heater which is in contact with the gripped straw. In the bonding section, an electric power supply rail is provided so that a collector of the heater slides on the rail, energizing the electric heater to heat the heat-bondable portion of the wrapped straw. In the bonding section, the heater is also pressed against the carton travelling in a production line at the same speed as the moving speed of the heater with the heat-bondable portion of the wrapped film therebetween. Thus one film wrapper is heat-bonded to each carton. After the completion of bonding, the cam operated gripper releases the straw allowing the straw to remain attached on the carton.

A method and apparatus for producing labeled, plastic foam containers, such as a labeled EPS cup uses a heated pocket to thermally bond a label to a plastic cup. Also described is a labeled plastic foam container, such as a labeled EPS cup, having high quality printing capabilities, sufficient stiffness, acceptable insulation and barrier properties and reduced production cost.
摘要:
A deep-drawn paper tray made of paper material, a method and an apparatus for manufacturing the tray, and a closed product package comprising the tray. The tray having a bottom and upwardly expanding side walls around the bottom, the side walls of the tray being shaped to expand through a plurality of circumferential steps dimensioned low enough for obtaining wrinkle-free side walls for the tray. The outermost step is a flat, wrinkle-free rim flange, which enables liquid and gas proof heat-sealing of a lid to form the package. The apparatus may comprise upper and lower moulding tools with concentric movable frames for forming the tray bottom and side wall steps from paper blanks, and moulding tools may be mounted onto a rotating turret carrying a paper blank through working stations arranged along the turret circumference, to shape the tray bottom and the side wall steps at the consecutive stations.

摘要:
A lightweight component is equipped with two cover layers, which are made of a wood material, and a filling disposed in between the layers after cutting everything to size, having an edge support including thermoplastic material. The edge support is anchored in both the first and second cover layers starting from the narrow side. Anchoring is achieved by bringing the edge support into contact with the respective cover layer and coupling mechanical vibrations into the edge support by a sonotrode engaging from the narrow side. The edge support at the same time is pressed against the cover layer such that, in the region of a transition between the thermoplastic material and the wood material of the cover layer, part of the thermoplastic material is liquefied and pushed into the cover layer material, thereby producing a positively engaged anchoring after hardening.

Mold system (1) for manufacturing cardboard-based container, comprising movable mold half (10) and stationary mold half (20) located opposite one another. Movable mold half (10), movable with respect to stationary mold half (20), includes at least a core plate (4), a plate-like seal ring (5) movable with respect to the core, and collar ring (6). Stationary mold half (40) includes at least a mold plate (7) provided with a mold cavity (71) and a seal surface (7a). In the mold system (1), an insert (720) can be supported on and detachably attached to the base (71b) of the mold cavity (71) reducing the depth H of the mold cavity by its height h. Container (500) comprises bottom (57) pressed from cardboard blank and wall (59) connected to the bottom and plastic rim (50) connected to the upper edge of the walls.
摘要:
Provided is a fine paper powder-containing resin molded object with a content of a thermoplastic resin being reduced to offer a lighter weight and a superior mechanical strength, and a manufacturing method thereof. The fine paper powder-containing resin molded object (1) is made from a thermoplastic resin containing fine paper powder and is composed of a non-foam layer (2) formed on the surface and a foam layer (3) formed in the inner side. The foam layer (3) has, in the order from the surface side, a first foam layer (3a) containing cells having an average cell diameter ranging from 10 to 100 μm, a second foam layer (3b) containing cells having an average cell diameter from 5 to 50 μm, and a third foam layer (3c) containing cells having an average cell diameter from 20 to 500 μm. The molded object (1) contains an aromatizing ingredient.
