A resin-junction body includes a first resin member, a second resin member including a concave portion and laminated on the first resin member so as to contact the first resin member at a contact surface. The concave portion comprises a bottom face on a first resin member side. The resin-junction body further includes a joining layer that joins the first resin member and the second resin member and that extends from the bottom face towards the first resin member.

A method of bonding a second object to a first object includes: providing the first object, which includes a thermoplastic liquefiable material in a solid state; providing the second object, which includes a surface portion that has a coupling structure with an undercut such that the second object can make a positive-fit connection with the first object; and pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool. The step of pressing and coupling vibrations into the tool continues until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object. Thereafter, the thermoplastic material of the first object is permitted to re-solidify to yield a positive-fit connection between the first and second objects.

A pipe processing apparatus, for forming branches on pipes made of thermoplastic material, including a base adapted to be fastened to the outer wall of a pipe and a supporting structure which extends from the base; a support member is slidingly associated with the supporting structure and is adapted to receive an interchangeable processing/handling means configured to interact with the pipe; the apparatus also includes a movement means which engages the support member in order to move it on command along a processing axis. The supporting structure includes a single elongated structural element.

A method for forming an engagement portion in a workpiece is provided, said workpiece preferably consisting at least partially of wood, materials containing wood fibers, wood composite materials, veneer, plastics materials and combinations thereof. The method has the following steps of: providing the workpiece having a cutout, introducing a predetermined volume of a curable filling compound into the cutout and introducing an engagement element into the curable filling compound, wherein the engagement element has an engagement structure which at least partially represents a geometric counterpart to the engagement portion, the engagement portion takes up a predetermined position in the workpiece, and the engagement structure is arranged at least partially in the filling compound.

A reinforcement and/or lining method is provided, wherein a thermoplastic reinforcement and/or lining element is subject to mechanical energy impact and mechanical pressure by a tool so that reinforcement and/or lining material of the reinforcement and/or lining element is liquefied and pressed into porous material to reinforce the porous material. In at least one axial depth, the reinforcement and/or lining element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the reinforcement and/or lining element and in second regions is not in contact with the reinforcement and/or lining element.

A paint roller manufacturing system includes a cover dispenser for continuously dispensing a windable width of paint roller cover fabric, a fabric supporting and advancing device for supporting the fabric and maintaining a width-wise dimension of the paint roller cover fabric as the fabric advances, a fabric coating applicator for applying a coating to the back side of the paint roller cover fabric while the fabric supporting and advancing device maintains the fabric in a width-wise dimension, and a compressing roller positioned downstream of the fabric coating applicator and configured to apply a compressive force on the coating after it has been applied to the back side of the paint roller cover fabric and while the fabric is supported by the fabric supporting and advancing device. In two-strip embodiments, first and second strip dispensers continuously dispense a first and second windable width of strip material. A guide system guides the first and second strip coming from the first and second strip dispensers to be wound about a mandrel and guides the coated paint roller cover fabric from the fabric supporting device to be wound about the first and second strips. An adhesive applicator is configured to apply adhesive on substantially all of the outer side of the first and second windable strips and positioned to apply adhesive to the outer side of the first and second windable strips upstream of a location where the coated paint roller cover fabric is wound about the first and second strips.

A machine for welding saddle connectors by polywelding, during pipe laying, includes a base which extends in a first direction, a clamp which can move along the base in the first direction, a bracket mounting means for detachably coupling the machine to a pipe arranged transversely to the first direction, and a means for detachably coupling the base to the bracket mounting means.

The invention relates to a punch for punching polymeric motor vehicle components, in particular bumpers, comprising a machine frame (1), at least one device for fixing a polymeric motor vehicle component (2) on the machine frame (1), and at least one punch device (3), wherein the punch device (3) comprises at least one punching tool (4) and at least one punching die (5). According to the invention, the punching tool (4) and/or the punching die (5) is/are fastened to a receiving device (6) of a movable carrier (7, 8), wherein the carrier (7, 8) has at least one further receiving device (6) for fastening at least one further processing apparatus (9, 10, 20, 30), such that the punch can be set to a new, different processing step involving the further processing apparatus (9, 10, 20, 30) by a movement of the carrier (7, 8).

An adhesive bolt for forming a fastening point to a workpiece has a head and a shank connected to the head. The shank is set up to be introduced into a cutout on the workpiece. An adhesive is situated in the region of the shank and the workpiece. The shank is configured to enter into a non-positive preliminary connection with a bounding face of the cutout until the adhesive has hardened.

A composite skin is attached to an underlying structure by fasteners that are countersunk into the structure. The composite skin comprises a thermoplastic material that has been melted and formed into a countersink in the structure using a heated tool.
