An applicator mitt assembly system comprises an applicator mitt tooling including: a tooling body having a mitt-perimeter cutter and weld bead thereon which are shaped to a perimeter of an applicator mitt to be cut; a heating element associated with the tooling body, the heating element being shaped so as to match or substantially match a shape of the weld bead so as to create a perimeter weld for the applicator mitt when engaged with the tooling body; and an ejector platen which is actuatable relative to the tooling body to eject a cut and welded mitt away from the tooling body. The system can further comprise a conveyor device adapted to feed uncut and unwelded mitt material towards the applicator mitt tooling and a tooling actuator adapted to actuate the applicator mitt tooling relative to the conveyor device.

A method of partially insulating an interior space of a pre-formed fluted core panel is disclosed herein. The fluted core panel includes a first facesheet, a second facesheet spaced apart from the first facesheet, and webs between the first facesheet and second facesheet. The interior space is defined between the first facesheet, the second facesheet, and adjacent webs. The method includes positioning a spacer in a first portion of the interior space, positioning a membrane between the spacer and a second portion of the interior space, and positioning insulation in the second portion of the interior space. Additionally, the method includes pressing the membrane against the spacer, curing the membrane, and removing the spacer from the first portion of the interior space.

A pipe-liner system for use when lining a pipe interior features a pipe having a pipe opening end and a pipe interior wall. The system features a flexible, substantially-impermeable, elongate extender-tube and an evertable, flexible, elongate, tubular pipe-liner. The system features a substantially leak-proof pressure retaining closure-sleeve located on a pipe-liner second end. An extender-tube second end is attached to a pipe-liner first end via a substantially leak-proof connection there between. The combined extender-tube and the pipe-liner form a single continuous evertable tube, hereinafter referred to as an extended liner having the pressure retaining closure-sleeve enclosing an extended liner distal end. A length of the extender-tube and a length of the pipe-liner are each chosen so that the liner is caused to be accurately positioned within the pipe upon eversion.

A hot pressing apparatus includes a positioning template having a forming region for placing a workpiece, a hot pressing template, a plurality of positioning blocks, and a lifting mechanism. A plurality of holes is formed in the forming region along a periphery of the forming region. The positioning blocks are movably disposed outside the forming region along the periphery of the forming region for positioning the workpiece in the forming region. The hot pressing template is movable between a hot pressing position and a releasing position for hot pressing the workpiece located in the forming region cooperatively with the positioning template when moving to the hot pressing position. The lifting mechanism includes a plurality of pillars movably disposed in the holes respectively and a driving device for driving each pillar to extend out from the corresponding hole so as to lift the workpiece.

An object of the present invention is to provide a method of joining sheet members together that is capable of joining two sheet members together without causing a stepped portion on a joined portion. Provided is a method of joining a first sheet member and a second sheet member together, which includes bringing an end face of the first sheet member into abutment with an end face of the second sheet member to provide an abutted portion, heating the abutted portion via a heating medium to thermal-fusion-bond the end faces with each other, and peeling off the heating medium from the first and second sheet members after the thermal-fusion bonding.

Provided are a filter manufacturing apparatus for fabricating a lower cap with an open upper portion and a lower cap welding portion therein, an upper cap with an open upper portion and an upper cap welding portion therein, and a non-woven fabric of a filter medium between the lower cap and the upper cap, the apparatus comprising a lower cap heating unit for melting only the lower cap welding portion (352) by mounting the lower cap (350) and heating a hot wire connected to an external power supply, a lower cap pressing unit for pressing the non-woven fabric (370) on the lower cap welding portion (352), an upper cap heating unit for melting only the upper cap welding portion (362) by mounting the upper cap (360) and heating a hot wire connected to an external power supply, and an upper cap pressing unit for pressing the non-woven fabric (370) bonded to the lower cap (350) by the lower cap pressing unit on the upper cap welding portion (362).
摘要:
A coupled portion of mutual laminate films sufficiently contributes to the formation of a packaging bag in that the coupled portion itself has excellent air tightness and liquid tightness. The tensile strength required for the laminate film is given to the coupled portion, whereby a temporary stop of a packaging apparatus is useless when a connecting portion of the laminate film is passed through the apparatus, thereby enhancing the operation efficiency and improving the yield of the material. Oriented base film layers are joined in a mitre form at the coupled portion between a rear end portion and a front end portion of laminate films comprising oriented base film layers and sealant layers.

There is disclosed a heat-sealing method including: feeding a fusible fiber sheet (12) into the clearance between a pair of rolls (1, 5), at least one of which has sealing ridges (2, 6) of a predetermined pattern on its outer circumference; and heating and pressing the fiber sheet (12) with the sealing ridges (2, 6), to form fused portions corresponding to the pattern of the sealing ridges (2, 6), in the fiber sheet (12). An insulator (4) is disposed to cover the outer circumference of the rolls (1, 5), as lacking the sealing ridges. The insulator (4) is made of a material which has a lower thermal conductivity than that of the sealing ridges and which can be elastically contracted by the pressure of the rolls (1, 5). The fiber sheet (12) to be fed into the clearance between the rolls (1, 5) rotating is compressed by the insulator (4) to discharge its internal air and is then heated and pressed by the sealing ridges (2, 6) so that it is heat-sealed.
摘要:
A cushioned bag has two adjacent multilayered sections comprising an outer layer of flexible thermoplastic material, a middle layer (or partial middle layer) of polyolefin film, and an inner layer of cushioning material. The sections are fused together along at least one edge of the bag to form a seamed edge comprising a fused bead. Apparatus for making a bag having a beaded edge includes cooperating heated jaws between which the bead is formed. A method of using the apparatus to make the bag includes rotating take-up rolls faster than feed rolls to pull the bag cleanly away from the jaws along the bead forming the seamed edge.

An ultrasonic welding tip assembly and associated method of use are described. The welding tips of the assembly may be conical with the cone height A and base width B having a ratio of A/B=1.2 or frusto-conical with a ratio of 0.76 in preferred embodiments. The welding tips are supported on anvils. In the welding process, the tips are only partially inserted into the material being welded so that the anvils remain spaced from the material. This space provides a reservoir into which molten material may flow away from the regions of the welding tips.
