A method and device for inserting a tongue in an insertion groove in a panel by a device, wherein the method includes: displacing a tongue guiding device in a first direction by displacing a puncher in the first direction, and displacing a tongue between a first part and a second part of the tongue guiding device and into an insertion groove in panel by further displacing the puncher.

An edge trim for pieces of furniture, including a meltable layer, is described. The molecular structure of the meltable layer contains both polar and non-polar parts. By way of a non-limiting example, an edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material is described, comprising a molten layer and a structural layer, wherein the structural layer and the molten layer are connected in an adhesive bond, wherein the molten layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure, wherein the molten layer contains energy absorbing additives, wherein the energy absorbing additives of the molten layer are selected from the group consisting of metal oxides, metal phosphates, metal salts of organic anions and combinations thereof.

A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; 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; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

A device for joining material by anchoring an insert comprising a first material in a structure comprising a second material is provided. The first material is solid and comprises thermoplastic properties and the second material is solid and is penetrable by the first material when in a liquefied state. The device comprises a vibration device being configured to transmit vibrations to said insert to cause at least partial liquefaction thereof and being arranged to move, relative to said structure, along an insertion direction (ID) to insert said insert at least partly into said structure, a contact sensor being connected to the vibration device and being adapted to move together with the vibration device along the insertion direction (ID), the contact sensor having a sensor body being adapted to detect contact with said structure. A controller is further connected to the contact sensor and adapted for receiving a contact signal from the contact sensor indicating that the sensor body has come into contact with said structure.

A device and a method are provided for setting a press-in element into a workpiece at a predetermined location. The device includes main body; a fixing unit, which is attached to the main body and which is designed to fix the workpiece; and a processing unit, which is attached to the main body and includes: a boring unit, which is designed to create a bore in the workpiece fixed by the fixing unit; and a pressing unit, which is designed to press a press-in element into the bore. The method fixes the workpiece; creates a bore in the workpiece; positions a press-in element over the bore; and presses the press-in element into the bore, wherein a single device is used to carry out the method.

Methods for forming rotor blades, rotor blade mold assemblies, and cores for rotor blade mold assemblies are disclosed. A method includes providing a first shell substrate on a first mold, providing a generally hollow core on the first shell substrate, providing a second shell substrate on the generally hollow core, and providing a second mold on the second shell substrate. The method further includes flowing a resin into a mold interior defined between the first mold and the second mold.
