A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; the molding strip is positioned on rotary drive means, the inside face of the molding strip being arranged to bear against the drive means; and molding material is dispensed against the outside face of the molding strip.

A method, apparatus, and system for reticulating an adhesive on a workpiece. The workpiece may be perforated with a plurality of passages that extend through a first side to a second side. To reticulate an adhesive on the first side of a workpiece, a flow of heated fluid is provided through a nozzle. The nozzle provides the fluid at a first pressure to a first group of the perforations. Once the temperature at the first side of the workpiece reaches a specified range, the fluid pressure may be increased or otherwise set in order to clear the perforations by forcing the adhesive out of or away from each of the perforations. Temperature of the adhesive, pressure within the nozzle, and/or light passage through the perforations may be monitored for logical control or quality assurance.

Provided is a workpiece bonding method that makes it possible to achieve a joining state with a high strength and to obtain a good repeatability of the joining state.

A workpiece bonding method according to the present invention is a workpiece bonding method for bonding two workpieces to each other, each of the two workpieces being composed of a material selected from the group consisting of synthetic resin, glass, silicon wafer, crystal and sapphire, the workpiece bonding method including: a surface activation step of activating a bonded surface of at least one of the workpieces; and a laminating step of laminating the two workpieces such that respective bonded surfaces contact with each other, and a pretreatment step of removing moisture from the bonded surface of the workpiece that is to be subjected to the surface activation step is performed before the surface activation step is performed.

An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module for receiving a first nonwoven fabric, a second nonwoven fabric, and at least one elastic strand therebetween. The second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges includes a first ridge and a pair of second ridges positioned on opposing sides of the first ridge along the circumferential axis. The first ridge defines a plurality of interspaced lands and notches, and the second ridges are configured to sever the at least one elastic strand when in close proximity to the first bonding module.

A glueless dustless composite flooring material system providing PVC-based flooring having waterproof layers providing different qualities of hardness, wear-resistance, sound deadening, and decorative patterns, avoiding the use of moisture-susceptible compressed dust filler, with layers fused together, avoiding the manufacturing complexity and delamination risks of using glue or adhesive, with a quickly-cured, UV-cured top coating providing long-lasting high performance and shortening and simplifying the manufacturing, which can be done in a sheet-form, essentially continuous-run manner, with an ability to quickly and simply change the optional design printing and texturing produced, and having an optional underlayment layer.

A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; and the molding strip is positioned on rotary drive means, comprising at least two rollers, the inside face of the molding strip being arranged to bear against the drive means.

A unitary fabric structure for use within a personal care absorbent article includes a composite of at least two functional components for fluid intake. The two functional components include a fibrous, liner functional component and at least one fibrous, surge functional component. The functional components are positioned immediately adjacent one another within the composite and held together directly to one another.

Methods and apparatuses for making laminated objects from composite materials are shown and described. An adhesion reducing material is applied with a moving printhead to the interfaces between object sections and waste sections of the layers of the objects to facilitate damage-free removal of the waste sections from the object sections. A rotating build platform allows the objects to be formed with the fibers of adjacent layers oriented at non parallel rotational orientations relative to one another. In certain examples, the adhesion reducing material is applied between opposing surfaces of layers wherein one surface is an object surface and the opposing surface is a waste surface. An infrared preheater preheats the side of a current layer being applied to a previous layer to a temperature sufficient to cause the composite adhesive to bond layers together. The infrared preheater and a pressure roller define a lamination assembly that traverses along a travel axis during a lamination operation.

The present invention concerns a multilayer element comprising a reinforcing material suitable for producing composite parts combined on at least one of the faces of same with a support layer characterized in that the reinforcing material and the support layer are combined by means of electrostatic forces, and a method for preparing such a material and a method for producing a composite part produced from at least one reinforcing material obtained from such an element, after having removed the support layer.

A process for joining fiber composite materials using self-piercing rivets. The process includes contacting first and second panels. The second panel is a fiber composite material. The process further includes elevating a temperature of only a fastening portion of the second panel. The process also includes placing the first and second panels on a die and joining the first and second panels with one or more rivets while the fastening portion is at an elevated temperature.
