A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine. Prior to cutting the continuously extruded strip-shape softened resin sheet (S) to the unit resin sheet (U) , the slits C.sub.1, C.sub.2, C.sub.3, C.sub.4 and C.sub.5 which promote the molding to the press molded part from the unit resin sheet (U) (improve an inflow property of the material) are formed by a cutter which is upwardly and downwardly driven by an air cylinder at a portion P.sub.3 in which the material therein is out of a range of the press molded products P.sub.1 and P.sub.2 obtained by press-molding the press molded product by using the press molding machine and becomes a scrap. The inflow property of the resin material for vertical walls and embossment portions when press-molding is improved and the defects of the product can be prevented.

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.

A filter support sheet extruded from a fluoroplastic material includes a base section having spaced-apart ribs extending outwardly from at least one surface thereof. Segments between spaced-apart ribs provide flow channels and apertures are punched through the sheet in a predetermined pattern unaffected by the structure of the support sheet. A method includes the steps of: (1) extruding a thermoplastic, fluoroplastic material to form of a sheet; (2) passing the sheet through a nip region provided by opposed rollers; at least one having an outer surface with counter-sunk grooves. Counter-sunk grooves in one roller are aligned with an outer surface or counter-sunk grooves of the other roller in the nip region to form a ribbed sheet having ribs upstanding from at least one surface of said sheet; (3) setting the ribbed sheet and (4) punching apertures through the ribbed sheet in a predetermined pattern.

A drainage component having a continuous, extruded mat having an upper face and a lower face. The mat includes a plurality of patterned three-dimensional structures, each structure spaced from all adjacent structures, and the plurality of patterned three-dimensional structures are provided in a plurality of linear rows or columns in a first direction.

The present application uses a thermoplastic resin as a substrate with the addition of a thermally conductive filler, a fire retardant and a toughener to jointly prepare a thermally conductive insulating sheet; the thermally conductive insulating sheet so prepared has thermally conductive, insulating, fire retardant and other properties, while a thickness of 0.05-1 mm can be attained. Furthermore, the present application uses a process of extrusion and rolling to prepare a thermally conductive insulating sheet with a thermoplastic resin as a substrate; the thickness can be precisely controlled, while it is possible to have no hole formation while ensuring a thin-wall state of the thermally conductive insulating sheet.

A method is described for forming a plurality of articles. The method includes creasing a tag substrate between first and second ends to form a first fold, wherein a first bent portion is defined between the first end and the first fold; lifting the first bent portion away from the central span to initiate elastomer to flow under the first bent portion; disposing the elastomer on at least a portion of a central span of the tag substrate; and bonding the elastomer to the tag substrate at a first connection zone, wherein a first elastomer portion extends along a rear surface of the first bent portion and a second elastomer portion extends along a front surface of the first bent portion.

Packaged viscoelastic polymer substances and methods for the production of the packaged viscoelastic polymer substances are provided. The packaged viscoelastic polymer substances are further processable under the influence of heat and shear.

This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.
