A three-dimensional object includes an outer-layer member and an inner structural member. The outer-layer member is a layer to constitute the surface of the three-dimensional object, and includes an inner space. The outer-layer member is made up of a plurality of divided outer-layer pieces formed of build material, which is functional ink ejected from a droplet ejection head and cured. The inner structural member is disposed in the inner space of the outer-layer member and configured to support the outer-layer member.

The present disclosure is directed to dunnage bags formed using polyethylene terephthalate (PET) and processes for manufacturing these PET dunnage bags. Generally, the PET dunnage bags of the present disclosure include a PET outer bag, an inner bladder enclosed within the PET outer bag, and a valve assembly that enables air to be introduced into (or escape out of) the inner bladder to inflate (or deflate) the inner bladder, thereby inflating (or deflating) the PET dunnage bag.

A welder for joining two polymeric sheets together using a wedged heating element allows for a heating profile on opposite faces of the heating element to be varied by controlling where each of the polymeric sheets contacts the corresponding face.

Provided is a thermal molding method for producing a thermally molded article having excellent abrasion resistance at its melt-fused part. Polyamide 6 and a copolyester are prepared separately. The copolyester contains terephthalic acid, ethylene glycol, and 1,4-butanediol as copolymerization units. The copolyester may further contain ε-caprolactone and/or diethylene glycol as a copolymerization unit. A multifilament yarn in which core-sheath type composite filaments each containing a core component and a sheath component at a ratio of 1 to 4:1 by mass are bundled is produced by a composite melt-spinning method using the polyamide 6 as the core component and the copolyester as the sheath component. Using the multifilament yarn, a product of filaments is produced by weaving, knitting, knitting and braiding, or braiding. The product of filaments is heated to melt the copolyester and fuse the core-sheath type composite filaments to each other while retaining the initial filament form of the polyamide 6, thus thermally molding the product of filaments.

The present disclosure relates to a composite article that may include a plastic component, and a silicone component bonded the plastic component. The plastic component and the silicone component may be bonded at an intersecting region between a first surface of the plastic component and a first surface of the silicone component. The intersecting region may include at least one of an acetone content of not greater than about 0.2 ppm, an MEK content of not greater than about 0.2 ppm, or a trimethylsilanol content of not greater than about 0.2 ppm.

A method for producing a fencing material including the steps of: providing a border material having an interior surface; providing a mesh material having a front and a back; treating the interior surface of the border material to produce a tacky border material surface; placing a portion of the front and/or the back of the mesh material against the tacky border material surface; pressing the tacky border material surface and the mesh material together; and thermally bonding at least some portion of the front and the back of the mesh material with the interior surface of the border material. The border material being a polyvinyl chloride, the mesh being a polyvinyl chloride material and/or a vinyl coated material.

A method of making a brush includes providing a plurality of first filaments, each having a first end and a second end; bringing the plurality of first filaments into a first predetermined shape such that the first ends are arranged side by side on a common contour; fixedly connecting the first ends so that a first pre-tuft having the first predetermined shape and a connected first end is formed; bringing a second tuft element having a first end and a second end together with the first pre-tuft into a second predetermined shape such that the first end of the second tuft element and the connected first end of the first pre-tuft are arranged side by side on a common contour; fixedly connecting the connected first end of the first pre-tuft and the first end of the at least second tuft element so that a final tuft having the second predetermined shape and a connected end is formed; and attaching the final tuft to a brush body by overmolding the final tuft's connected end with a plastic material.

Motor vehicle sub-assembly (10) comprising a first part (20) made of plastic material forming an outer bodywork skin, and a second part (30) made of plastic material forming an internal structure to which said first part (20) is attached, characterised in that the second part (30) comprises at least one mechanical reinforcement (40) made of thermoplastic material having a Young's modulus less than that of the plastic material of the second part (30), and a coefficient of elongation at break greater than that of the plastic material of the second part (30).

A method for producing a composite glass pane, includes placing a first glass pane having a thickness less than or equal to 1 mm on a support mould, wherein the first glass pane is curved into a shape determined by the support mould; placing at least one thermoplastic film on the first glass pane; placing a curved second glass pane having a thickness greater than or equal to 1.5 mm on the thermoplastic film; and joining the first glass pane to the second glass pane via the thermoplastic film to form a composite glass pane by lamination.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.
