Method and arrangement for manufacture of a product or completion of a product
The invention relates to a method for manufacture of a product or in completion of a product. A flexible mat (20) is manufactured from an incompletely cured thermo-setting plastic, wherein the mat comprises an article (10) of electrically conductive material. The incompletely cured mat (20) including the article (10) is then formed as a function of a forming tool or to lie against or for contact with a product, whereafter final curing of the mat (20) is executed by supplying electric power to the article (10) or by external heat application or ultraviolet light. The invention also relates to an arrangement and uses.
System and method for thermoplastic welding using an induced thermal gradient
A system and method for thermoplastic composite welding comprising a cooling means and a heat source. The cooling means cools a heat-side laminate so as to create a thermal gradient in the heat-side laminate. The heat source heats the heat-side laminate after the cooling step is initiated but before the thermal gradient dissipates so that a first side of the heat-side laminate closer to the heat source does not deform as faying surfaces of the heat-side laminate and another laminate farther away from the heat source are welded together.

HORIZONTAL PACKAGING MACHINE WITH ADJUSTABLE CUT-SEW GROUP
A horizontal packaging machine (M) for packaging a product (P) fed in a horizontal direction (X) comprises a cut-sew group (22) for making on a packaging film (F) transverse welds and a cut to close and separate from each other two successive packs (C1, C2, C3, C4), wherein the cut-sew group (22) comprises a plurality of cut and sew tools (U1, U2, U3) for making the transverse welds and the cut, wherein the transverse welds define the edges of the packs (C1, C2, C3, C4) according to different packaging sizes for the product (P), wherein the cut-sew group (22) comprises an upper shaft (AS) and a lower shaft (AI) driven in rotation independently by means of a respective upper motor (MS) and a respective lower motor (MI), in which each shaft (AS, AI) mounts on it the plurality of cut and sew tools (U1, U2, U3) and in which each cut and sew tool (U1, U2, U3) is composed of an upper tool (US) and a corresponding lower tool (U1). In particular, the horizontal packaging machine (M) includes compensation means of the mutual distance (MMV, PE, P1, P2, CT, FL) between the two shafts (AS, AI) with micrometric adjustment of the distance to compensate for thermal expansion and use of packaging film (F) of different thickness.
METHOD AND APPARATUS FOR CONTROLLING INDUCTION WELDING
A method is provided for controlling an induction welding operation. The method includes sweeping electrical current through an induction welding coil at an initial position of the induction welding coil along a weld path of a material; monitoring a response of the material to the swept electrical current using at least one electromagnetic field (EMF) sensor; calibrating an electrical current value for the induction welding operation using the monitored response; and performing the induction welding operation along the weld path using the calibrated electrical current value.
Joining method
A method for joining primary and secondary members includes providing a primary member, a secondary member and a heating element which is joined to one of the primary and secondary members. The heating element includes an electrically insulating matrix material and an electrically conductive reinforcing element extending through the matrix material. The method further includes bringing the other of the primary and secondary members and the heating element into engagement and controlling a flow of electrical current in the reinforcing element so as to resistively heat and fuse at least some of the matrix material of the heating element with a matrix material of the other of the primary and secondary members. The method may be used to join a primary member such as a composite tubular and a secondary member such as a component for terminating the composite tubular.
Low mass staking module
A low mass staking module includes a punch having a cavity on a first side, a contact surface on the second side opposite the first side, and a circular flange extending about an outer edge thereof, the punch formed of a thermally-conductive material, an annular housing engaged with the punch about the circular flange at a first end, and a heating element located inside the annular housing. The heating element has an output side in contact with the contact surface of the punch, the contact surface having a shape conforming to a shape of the output side of the heating element. The punch is desirably a low thermal mass punch, while the heating element may be a high power (watt) density, solid state, ceramic, resistant heating element (e.g., aluminum nitride or boron nitride heaters).

Temperature sensing induction heating tool
An induction heating tool that holds voltage or current supplied to the induction tank circuit constant and tracks changes in the other of voltage or current during each induction heating cycle. The disclosed induction heating tool exploits the fact that the resistance an attachment plate increases along with the temperature of the attachment plate. During an induction heating cycle, the attachment plate is magnetically coupled to a work coil and the resistance of the attachment plate is reflected to the circuit. Changes in the resistance of the attachment plate alter the pattern of energy delivery from the work coil to the attachment plate in a predictable way. Calculations accurately predict the temperature of the attachment plate over a wide variety of ambient conditions, including the presence of moisture at the membrane/attachment plate interface. The disclosed induction heating tool produces consistent results without calibration for ambient conditions.
