A synthetic quartz glass substrate is machined by bringing a surface of the synthetic quartz glass substrate as the workpiece into contact with and superposing it on a surface of a protective member made of synthetic quartz glass to effect optical contact bonding of the workpiece and the protective member, and passing a cutting tool through the optical contact bonding surfaces. This machining process is able to effectively prevent the generation of microdefects at the cutting tool entry site and extraction site during a cutting operation. Moreover, a fixing agent is not used to join the workpiece and the protective member, and so productivity is high because there is no need for the application and later removal of a fixing agent.

A wound dressing having a thin barrier layer of soft, pliant adhesive material with a flexible cover layer extending along one side of the adhesive layer and a removable release sheet on the opposite side is disclosed. The adhesive material has a center and border surrounding the center such that the adhesive is contoured. A method for making the contoured dressing using a gear pump and a laminating roller having a predetermined softness and firmness is also disclosed.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A method for making a badge includes laminating a printed substrate with a back side laminate sheet and a front side laminate sheet and disposing a barrier sheet between at least one of the back side laminate sheet and the printed substrate and the front side laminate sheet and the printed substrate. And a side loading pocket section is formed between at least one of the back side laminate sheet and the printed substrate and the front side laminate sheet and the printed substrate.

A device and a method for connecting sheet metal parts to form lamination stacks in which sheet metal parts are separated from an electrical steel strip using a stamping stage equipped with a punch, wherein the electrical steel strip has a thermally activatable hot-melt adhesive varnish layer on at least one of its flat sides, the separated sheet metal parts are stacked and integrally bonded to one another to form multiple lamination stacks through activation of the hot-melt adhesive varnish layer, wherein a parting compound is applied to the electrical steel strip and/or separated sheet metal part in order to make it easier to divide the stacked sheet metal parts into lamination stacks. In order to achieve advantageous conditions, it is proposed for the punch of the stamping stage to apply a liquid fluid as a parting compound onto the electrical steel strip and/or separated sheet metal part.

In order to provide a laminating apparatus that enables a film to be loaded in a reliable and easy manner without a complicated structure, a laminating apparatus 1 includes a sheet feed mechanism unit 10, a film cassette 20, and a press-bonding mechanism unit 30 configured to perform thermal press-bonding while sandwiching a sheet with a pair of films. The laminating apparatus 1 also includes an openable/closable upper unit 5, and employs a configuration in which the upper unit 5 is provided with one pressing roller 31 of a pair of pressing rollers of the press-bonding mechanism unit 30, and an upper member of another mechanism for performing a process in a state where the sheet is sandwiched between the films.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, a method of forming an insulation product may include forming a continuous sheet of paper into a plurality of flexible loops defining a plurality of air channels extending in a direction that is substantially perpendicular with a machine direction of the continuous sheet of paper. The method may also include immediately attaching a first layer of paper and a second layer of paper to the plurality of flexible loops as they are formed so that the continuous sheet of paper retains the plurality of flexible loops between the first layer and the second layer and that the plurality of flexible loops remain unattached with respect to one another.

A scrap collection assembly for a tape lamination head that applies a plurality of composite tape segments includes a crack-off assembly with a scrap crack-off redirect roller configured to engage one or more composite tape segments and one or more scrap portions; a secondary crack-off roller configured to engage one or more composite tape segments and one or more scrap portions; a pivot that connects the crack-off assembly to the tape lamination head, wherein the secondary crack-off roller selectively moves about the pivot to change a direction of composite tape movement; and a conveyor that receives the scrap portion(s) from the secondary crack-off roller.

An assembly for producing cabinet doors including a CNC machine provided with a porous worktable, means for positioning workpieces thereon, means for applying a vacuum to such porous worktable for adhering such workpieces thereto and means for machining such workpieces adhered to such worktable; and means for thermally deforming a thermally pliable foil to laminate such workpiece.
