A method for welding two hollow profiled rods made of plastic to form a window frame. The profiled rods to be joined together are heated to a predetermined temperature by inserting a welding plate between their connecting surfaces and pressing the same against the welding plate, forming outer and inner beads, and the profiled rods are pressed together under pressure after removing the welding plate, with a simultaneous increase in the size of the weld bead. For all cross sections of the profiled rods and the plastics used for manufacturing the window frames, to obtain a type of shadow groove on the top side and/or front side and on the bottom side and/or rear side of the finished window frame in the area of or near the connecting sites of the finished window frame, only the outer beads formed on the visible surface of the subsequent window frame in the area of or near the connecting sites of the two profiled rods are pressed slightly inward after removing the welding plate forming an oblique edge, and then are removed together with the inner beads, and then the connecting surfaces of the two profiled rods are joined together.

An article of footwear can comprise: an upper, and a sole assembly connected to the upper to form a receptacle for a human foot, the sole assembly can comprise: a cushion comprising an exterior wall that forms an enclosure; an antenna disposed within the enclosure; and a microchip connected to the antenna. A method of manufacturing an article of footwear can comprise: positioning an electronic communication device between two plies of polymer laminate; heating the two plies of polymer laminate to form a weld area and a cushion area, wherein the electronic communication device becomes encapsulated between the two plies of polymer laminate, inflating the cushion area with a gas; and sealing the cushion area.

A method is provided for managing the temperature of heat sensitive material located near a repair patch being thermally cured on a composite skin using a heating blanket. The method comprises configuring an assembly of thermally conductive cooling blocks to fit within a space between the heating blanket and the heat sensitive material. The assembly of thermally conductive cooling blocks is then installed against the skin within the space, forming a heat sink that conducts a portion of heat out of the composite skin away from the heat sensitive material.

A system for, and method making and repairing a fiber-reinforced component including bonding a first thermoplastic matrix possessing reinforcing fibers distributed therein to a second composite member possessing a thermoplastic matrix with reinforcing fibers distributed therein; and metals and more particularly a method and apparatuses for joining fiber reinforced thermoplastics utilizing a combination of heat, force and rotational force.

The present invention relates to the use of dual ovenable biaxially oriented polyester films in vacuum skin packaging applications. Furthermore, the invention relates to preferably dual ovenable skin packages, in particular to preferably dual ovenable vacuum skin food packages for cook-in applications. Due to the very high formability, the VSP packages of the present invention do not show the defects of prior VSP ovenable packages such as self-sealing of the top web or unsealed areas around the packed product.

The present disclosure provides a process. In an embodiment, the process includes A. providing a fitment with a base, the base comprising an ethylene/-olefin multi-block copolymer; B. placing the base between two opposing multilayer films, each multilayer film having a respective seal layer comprising an olefin-based polymer; C. flat sealing the base to each multilayer film with opposing heated flat seal bars, the flat sealing forming opposing seal joints at the flattened base ends; and D. point sealing the opposing seal joints with opposing curved seal bars.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

The present disclosure is concerned with a method of forming a seal with a polyethylene based film structure. The polyethylene based film structure has at least one layer formed with an oriented polyethylene having a predetermined melting temperature (T.sub.m). A conductive heat sealing device provides heat to form the seal, where a first sealing bar of the conductive heat sealing device operates at a first operating temperature of at least 10 degrees Celsius (? C.) below the T.sub.m of the oriented polyethylene in the polyethylene based film structure and a second sealing bar of the conductive heat sealing device operates at a second operating temperature of at least 15? C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.

A technique for accurately detecting a temperature of a sealing surface which is not affected by sealing conditions or the like is provided. A seal bar (1) is a rod-shaped seal bar having a sealing surface (11a) and includes a heater (13) and a temperature sensor (14). The heater (13) is provided in a main body of the seal bar (1) and extends in an extending direction (D1) of the main body (11). The temperature sensor (14) is provided at a position between the sealing surface (11a) and the heater (13) in the main body (11) of the seal bar (1) and is inserted into the main body (11) of the seal bar (1) from an end surface (upper end surface (112) or the like) which intersects a long side of the sealing surface (11a).
