The invention relates to an anchor for arrangement in lightweight building boards, wherein a lightweight building board has a first covering layer and a second covering layer made from compact material that is stiff in compression, and a core layer, which is arranged between the covering layers and is made from material with a low density in comparison with the covering layers, in particular paper honeycomb, foam or solid wood of low density, having a first anchor part and a second anchor part, wherein the first and the second anchor part are designed to be movable relative to one another, in which a travel between a first end position and a second end position is limited, wherein the first end position is defined by means of first stop means on the first and the second anchor part, and the second end position is defined by means of second stop means on the first and the second anchor part.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. 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. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

An apparatus for applying a cellulose-based annular body to a perimeter flange of a container includes a supporting unit and an operating unit. The supporting unit has a seat to receive a body of the container and is surrounded by an annular portion on which the annular body and the flange rest, such that the annular body is interposed between the annular portion and the flange. A heating device heat the annular body. The supporting unit includes an annular recess, surrounding the annular portion, to at least partly house an annular end bead of the flange. The apparatus includes a forming device, movable along a respective axis of movement between a far position and an engaging position. In the engaging position, the forming device engages and deforms the annular bead pushing said annular bead into the annular recess.

A method of fastening at least one second object to at least one first object, wherein mechanical vibration acts from a sonotrode on the second object to fasten the second object to the first object. Between the sonotrode and the second object, an auxiliary sheet is placed, for example of paper. After the vibration stops, the auxiliary sheet is displaced relative to the sonotrode for a next fastening step.

A method of anchoring a connector element (10) in a receiving object (66) comprises inserting a distal end of the connector element (10) into a mounting hole in an insertion direction along an insertion axis; inserting a sleeve (36) comprising a thermoplastic material into the mounting hole, the sleeve (36) enclosing the connector element (10); and transferring energy to liquefy at least a portion of the thermoplastic material of the sleeve (36). A machine (500) configured for carrying out the method and a connector element anchoring kit comprising a connector element (10) and a sleeve (36) comprising thermoplastic material.

A three-dimensional decorative piece that is made of a thermoplastic synthetic resin and can retain bulkiness and shape by a core and a method of producing the same. The three-dimensional decorative piece includes an upper layer molded body made of an upper layer material with a metal vapor-deposited layer and having a three-dimensional shape with a convex portion formed on its front surface side through a high-frequency dielectric heating, a core formed by curing a flowable synthetic resin filled in the convex portion of the upper layer molded body, and a substrate bonded a back surface side of the core by fusion.

An apparatus for heat-sealing a lidding film (2) to a supporting element (3), comprising a movement track (5), which extends between an infeed zone and an outfeed zone, a conveying unit (8) and a heat-sealing device (6) which is fitted along the movement track (5), the device (6) comprising a supporting unit (10) and a closing unit (11) which are movable between a home position in which they are at a distance from each other and an operating position in which they are coupled to clamp, in use, the lidding film (2) and a supporting element (3); wherein the conveying unit (8) is configured to support the supporting element (3) and to move and is associable with the movement track (5) for moving on it; the conveying unit (8) comprising one or more active portions (12) which are configured to support the supporting element (3) from below and to couple to the supporting unit (10) to define with it a clamping unit for clamping the supporting element (3) against the closing unit (11).

A method of anchoring a connector element (10) in a receiving object (66) comprises inserting a distal end of the connector element (10) into a mounting hole in an insertion direction along an insertion axis; inserting a sleeve (36) comprising a thermoplastic material into the mounting hole, the sleeve (36) enclosing the connector element (10); and transferring energy to liquefy at least a portion of the thermoplastic material of the sleeve (36). A machine (500) configured for carrying out the method and a connector element anchoring kit comprising a connector element (10) and a sleeve (36) comprising thermoplastic material.

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 tool for pressing a foamed material onto a substrate, a manufacturing apparatus thereof, and a method for manufacturing a laminated structure of a heat-retaining container are disclosed. The tool comprises a body, a blade portion extending in a lengthwise direction from the body, and a press portion extending in the lengthwise direction from the body and configured for pressing the foamed material onto the substrate. The tool may be used to press a foamed material sheet onto a paper substrate and form a tear line on the foamed material sheet at the same time to simplify the manufacturing process of the laminated structure of a heat-retaining container.
