A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.

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.

According to a method or an apparatus for fastening bristles in a bristle carrier (10) without using an anchor a heating (39) is provided in a tool part configured to transport the bristles. After inserting the bristles into anchoring openings (12) in the bristle carrier (10), the anchoring openings are closed by applying pressure.

The invention relates to an apparatus and to a method for establishing a connection having material continuity or having material continuity and shaping matching or for separating such a connection of at least one metal or ceramic component and of a component formed from or by a thermoplastic polymer in which the components to be joined together can be pressed together by a pressing device having a counterholder and a plunger. A heating device is present at the plunger and/or at the counterholder or acts there. A heating of the at least one metal or ceramic component up to above the softening temperature of the component formed from or by polymer can be achieved with the heating device, with the heating device being having at least one electrical resistance heating element that is covered by an electrically insulating, preferably ceramic, protective film, and/or having at least one laser beam that is directed to the metal component(s) within the joining region, and/or having at least one inductor present at the plunger and/or at the counterholder for the inductive heating of the meal component(s).

A porous body belt includes a body to be connected including a porous body, a connecting material A that is disposed on the body to be connected by spanning a gap between end portions of the body to be connected and contains a fiber A and a resin material A, and the resin material A penetrates at least a part of a void portion of the porous body of the body to be connected, and bonds the end portions of the body to be connected to each other.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

The invention provides improvements to electrofusion fitting methods that allow for continuity and repeatability of welds between an electrofusion fitting and a pipe lining (or stand-alone pipe). An electrofusion fitting for joining sections of lined pipe has heating elements configured to create at least one weld between the electrofusion fitting and a pipe lining, however prior to the weld step taking place the electrofusion fitting is heated and expands accordingly to ensure contact with the pipe lining. Preheating the electrofusion fitting also provides a predetermined starting temperature for the fitting and the lining which results in improved fusion cycle reliability. Furthermore, the need for clamps or support frames to support the electrofusion fitting in situ is removed, with corresponding reductions in cycle times, complexity, and hence cost.

Provided herein are apparatus and methods for film sealing dies, and in particular, to apparatus and methods for film sealing dies in form, fill and seal (FFS) processes. An apparatus for sealing plastic film materials includes a heating mechanism, the heating mechanism including a heating lip (110) arranged such that when a plastic film (120) is contacted with the heating lip (110), the heating lip (110) forms a hot seal on the plastic film (120); and a cooling mechanism, the cooling mechanism comprising a gas jet duct oriented to contact the hot seal on the plastic film (120) at a contact angle between 0 and 60 such that the hot seal formed on the plastic film (120) is cooled to a temperature of less than or equal to 40 C. in less than or equal to 5 seconds to form a sealed plastic film.

A connection element includes a composite component with a cured epoxy resin, a first layer including a first thermoplastic polymer and an intermediate layer arranged between the composite component and the first layer, the first layer containing both the cured epoxy resin of the composite component and the first thermoplastic polymer of the first layer. The first thermoplastic polymer has a melting point above a curing temperature of the epoxy resin and is soluble at a temperature of at least 150? C. in the epoxy resin used for producing the composite component.
