A device for welding profiled elements in plastic material includes: a base frame supporting retaining members of respective profiled elements, to engage the profiled elements with corresponding zones to be welded facing one another; a heater for heating the weld zones of the profiled elements; a unit to move the retaining members, to shift the profiled elements between a first reciprocal away direction and a second reciprocal closer direction wherein the zones to be welded are coupled together; and a removal unit utilizing milling The removal unit includes: a supporting frame positioned in correspondence to the retaining members; at least one machining tool; a motor part associated with the tool; and a movement member of the tool, to move it between a first idle condition and a second working condition wherein it is placed between the profiled elements.

A method for welding profiled elements in plastic material includes: preparing two profiled elements, arranged with respective weld zones facing one another; making a groove corresponding to at least one weld zone of the profiled elements, the grooving performed by a removal operation on a peripheral edge of at least one profiled element; heating the weld zones; coupling the zones to be welded to one another, pressing the profiled elements together to keep the zones to be welded in reciprocal contact. The coupling step includes: a sub-step of melting the zones to be welded into one another in order to define a welding bead; a sub-step of making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and the step of arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

A material deposition technique is disclosed for transferring material to a substrate. The material may be a foil on a carrier and the substrate may be printable paper. A computer-controlled, material application subsystem is provided having a material roller assembly including one or more material pressing rollers. The entire assembly is configured for controlled rotation such that the material pressing rollers alternately engage and disengage an impression cylinder. In a first rotatable position, the material roller assembly is rotated so that one of the material deposition rollers over which the material carrier is fed engages the impression cylinder and deposits the material onto the substrate as it passes beneath the roller. In a second rotatable position, the material roller assembly is rotated so as to disengage the material roller from the impression cylinder thereby precluding deposition of material onto the substrate as it passes beneath the roller.

Disclosed herein is an improved cover board product with a panel comprising a top surface layer comprised of paper or a fiberglass web; a bottom surface layer comprised of paper, a fiberglass web, nylon film, polyester film, polypropene film, or textiles; and a core layer comprised of paper and thermoplastic fragments connected by a thermoplastic bonding resin. The thermoplastic bonding resin is in a random pattern to less than 100% of the paper and thermoplastic fragment surface area.

Snowboards are constructed by initial manufacture of a base sub-assembly including fewer than all layers of the snowboard, e.g., a base layer, edges, and a stabilizing layer. These layers are permanently bonded together into a unitary base sub-assembly. The running (bottom) surface is then finished to provide a desired surface consistency by eliminating undesired irregularities from the manufacturing process, e.g., using a conventional base grinding machine. Subsequently, the base sub-assembly and remaining snowboard layers (e.g., top sheet and a core sandwiched between reinforcing layers) are permanently bonded together into a unitary final snowboard assembly, which may then be worked to form a finished snowboard. Snowboards may be either flat or non-flat in both the longitudinal and transverse directions. Accordingly, the method may be used to produce snowboards having a desired sanded/ground base surface having a desired surface consistency, even for snowboards that are non-flat in the transverse direction.

An embroidery simulation system and method configured to create desired artwork on a readily attachable base member having the appearance of simulated embroidery is disclosed. The system and method are configured to enable an emblem to be created that resembles embroidery and is configured to enable the emblem to be attached to goods, that were traditionally embroidered, in a fraction of the time previously needed to embroider that same article. In addition, the emblem to be created by the system and method may be attached to goods that traditionally we unable to be embroidered, such as drinking mugs and other hard surfaced goods. The embroidery simulation system and method enhance the flexibility of a company by increasing the type and diversity of product to which an emblem can be affixed while also reducing inventory requirements for resellers of goods.

A filler material is applied to a plurality of wood elements. The plurality of wood elements is bonded into a composite wood product, where the bonding includes delivering ultrasound energy to the plurality of wood elements. The ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz.

The embodiment of the present invention discloses a bonding device. The bonding device includes a main body and a lamination part connected to the main body. The lamination part is configured to press and bond an adhesive layer to an apparatus to be bonded, and includes a lamination main portion and a squeeze sub-portion connected to the lamination main portion. Along a lamination direction perpendicular to the lamination part, a width of the squeeze sub-portion is less than a width of the lamination main portion. The present invention, by using the squeeze sub-portion of the lamination part with a smaller width, more conveniently squeezes and bonds the adhesive layer, which facilitates mechanized bonding, improves a bonding efficiency, and reduces a labor cost while guaranteeing a bonding effect.

A graphene copper composite material preparation method based on a combination of hot pressing sintering and chemical vapor deposition, comprising: presetting multi-layer copper foil in a hot pressing chamber; preparing a graphene thin film on the surface of the copper foil by means of a chemical vapor deposition method to obtain a graphene copper composite material; and then performing hot pressing forming on the multi-layer graphene copper foil material to prepare the graphene copper composite material. Said material can replace a traditional copper material or silver material, is applied to a supercapacitor or a motor driving device, and has the effects of improving efficiency, reducing temperature rise, etc.

A laminating device includes: a plurality of laminating heads that each holds a unit laminated body; a drum section in which the plurality of laminating heads are arranged, which holds each laminating head swingably via a support shaft, and which rotates to advance each laminating head to a laminating position facing a lamination stage; a cam section which is in contact with each laminating head and which causes each laminating head to swing around the support shaft in association with a movement of each laminating head caused by a rotation of the drum section; and a biasing member that biases each laminating head in a radial direction of the drum section.
