A method for manufacturing a microprojection unit (10) according to the invention involves: a microprojection tool forming step of forming a microprojection tool (1) by bringing a projecting mold part (11) into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and thus forming a protrusion (3) that protrudes from another surface (2U) side, and withdrawing the projecting mold part (11) from the interior of the protrusion (3); a joining step of joining the one surface (2D) side of the base sheet (2A), in which the microprojection tool (1) has been formed, and a tip end of a base component (4); and a cutting step of cutting the base sheet (2A), to which the base component (4) has been joined, along a contour (4L) of the base component (4) at a position more inward than the base component's contour (4L) in a planar view of the base sheet (2A) as viewed from the microprojection tool (1) side, to manufacture a microprojection unit (10).

The present disclosure generally relates to devices and methods for furniture protection. More particularly, the present disclosure relates to foam-film sheets configured to protect furniture from damage. An exemplary foam-film sheet as disclosed herein includes a sheet of foam material having a first lateral edge and a second lateral edge; a sheet of film material having a first lateral edge and a second lateral edge; a first seal between a portion of the foam material proximate its first lateral edge and a portion of the film material proximate its first lateral edge; and a second seal between a portion of the foam material proximate its second lateral edge and a portion of the film material proximate its second lateral edge, wherein the film and foam are substantially unsealed along the entire transverse width between the first and second sealed portions near the lateral edges of the foam material.

A piece of substrate material is formed under heat and pressure by a roller against a cavity or platen into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate is coated with a dope in a casting device having a guide portion corresponding to the shape of the substrate sheets and quenched to form a filtering membrane.

A method of manufacturing a lightweight building element assembly is disclosed. The assembly firstly comprises a first object (1) being a lightweight building element that has a first outer building layer (11) and an interlining layer (13). The assembly further comprises a second object (2) secured to the first object. The method comprises firstly providing the first object, wherein the first object has an indentation (19) formed by the first outer building layer. The indentation may form a blind opening or a through opening in the first object. The method further comprises providing the second object (2), wherein the second object comprises an outer surface portion of a thermoplastic material, wherein the outer surface portion is a lateral outer surface portion with respect to an axis. The second object is brought in contact with the first object so that the lateral outer surface is in physical contact with the sidewall (14), and mechanical energy is coupled into the second object so as to cause energy absorption due to friction between the lateral outer surface and the lateral wall, until a flow portion of the thermoplastic material becomes liquefiable and flows relative to the lateral wall. After re-solidification of the thermoplastic material, the flow portion secures the second object to the first object.

The present invention relates to a method for evaluating an assembly by welding of parts made of thermoplastic materials, to a test piece and its associated uses, to an installation for implementing this method and to the associated welding system.

A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.

A method of producing a preformed pavement marking prior to application to paving on the ground comprises: providing a first sheet (10a) of thermoplastic pavement marking material; providing a second sheet (10b) of thermoplastic pavement marking material; positioning the first and second sheets (10a, 10b) next to each other; transferring energy to an energization zone (28) along an edge of at least one of said first and second sheets (10a; 10b), to locally liquefy a portion of the thermoplastic material of said at least one of the first and second thermoplastic pavement marking material sheets (10a, 10b) in the energization zone (28); and solidifying the liquefied thermoplastic of the energization zone (28) to form a bond between the first and second sheets (10a, 10b).

A method of producing a golf ball applies ultrasonic welding on two half shells to form at least one intermediate layer, at least one cover layer, or at least one intermediate layer and at least one cover layer. The ultrasonic welding may include pressing the two half shells together, delivering a high power electrical signal to a welding stack, and converting the high power electrical signal at the welding stack to ultrasonic energy. The converting may include converting the high power electrical signal into a mechanical vibration, modifying an amplitude of the mechanical vibration to generate a modified mechanical vibration, and applying the modified mechanical vibration to an interface of the two half shells to weld them together ultrasonically. Aspects also relate to golf balls, or one or more layers thereof, made using ultrasonic welding.
