Method for deforming a web
Methods for deforming a multilayer web are disclosed. Steps of the method include: supplying a first layer of a precursor web; supplying a second layer of the precursor web onto at least the first area of the first layer; forming a plurality of first features and a plurality of second features in the precursor web. The plurality of first features are apertures formed in a first area of the precursor web, and the plurality of second features are formed in a second area of the precursor web in a positive and/or negative Z-direction. The plurality of first features and the plurality of second features are formed simultaneously.
METHOD FOR TRANSFERRING AN EMBOSSED STRUCTURE TO THE SURFACE OF A COATING AND COMPOUND STRUCTURE CONTAINING SAID COATING
The present disclosure relates to a method for transferring an embossed structure to at least a part of a surface of a coating (B2), using a composite (F1B1) composed of a substrate (F1) and of an at least partially embossed and at least partially cured coating (B1), where the coating (B2) and the coating (B1) of the composite (F1B1) have embossed structures which are mirror images of one another. Also described herein is a composite (B2B1F1). Further described herein is a use of this composite for producing an at least partially embossed coating (B2) in the form of a free film or a composite (B2KF2) composed of a substrate (F2), at least one adhesive (K), and the coating (B2).
AN EXTRUSION AND/OR PULTRUSION DEVICE AND METHOD
A method and an extrusion- or pultrusion device (1) for forming a profile product (2) made from a material in a production direction (Y), said device comprising: a rotating die (3), extending in a radial (R) direction and a width direction (X), having two opposite first and second side walls (5, 6) and an outer circumferential surface (4) extending in the width direction (X) there between, wherein the rotating die (3) comprises a first side portion (23) in connection to the first side wall (5) and a second side portion (25) in connection to the second side wall (6) and a mid-portion (22) extending between the first and second side portions (23, 25), and a profile definition zone (7) having a longitudinal direction (Y) coinciding with the production direction (Y), a height direction (Z) and a width direction (X) being perpendicular to the height direction (Z), comprising a through channel (8) comprising a first channel section (9) followed by a second channel section (10) downstream the first channel section (9) with reference to the production direction,
wherein the rotating die (3) is rotatable about an axis extending across the production direction (Y) and arranged to allow the outer circumferential surface (4) to, while the rotating die (3) rotates, exert a pressure onto a surface of the material when fed through the profile definition zone (7).
Touch fasteners and methods of formation
Aspects disclosed herein relate to forming on a substrate fastener elements suitable for use in touch fastener by employing vibration forming methods. The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques. Further, the product made can embody a variety of different configurations suitable for a given application. Employing vibration forming methods, such as ultrasonic forming methods, allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.
FORMING FASTENER ELEMENTS
Arrays of male fastener elements are formed by molding preforms in cavities defined in one or more adjacent plates and shaped to mold preform arms that extend to a plate side, such as in a cross-machine direction of a continuous molding process. The preforms may be deformed to flatten their upper surfaces and lengthen the arms. Stems of preforms have molded side surfaces and each have width, measured in the longitudinal direction of the strip, that narrows with distance from the strip surface, and also narrows with distance from a parting line extending from the strip surface to the head between the arms.
METHOD FOR TRANSFERRING AN EMBOSSED STRUCTURE TO THE SURFACE OF A COATING MEANS AND COMPOUND STRUCTURE USABLE AS AN EMBOSSING DIE
The present disclosure relates to a method for transferring an embossed structure to a surface of a coating composition (B2a), which includes the steps (1-i) and (2-i) or (1-ii) and (2-ii) and also the steps (3) and optionally (4), where the steps (1-i) and (2-i) or (1-ii) and (2-ii) are performed using a composite (F1B1) which is employed as an embossing die (p2) of an embossing tool (P2) and which is composed of a substrate (F1) and of an at least partially embossed and at least partially cured coating (B1), and the coating composition (B1a) used for producing (B1) of the composite (F1B1) is a radiation-curable coating composition of defined constitution. Also described herein is a composite (F1B1).

Eyelet for biomedical electrode and process for production thereof
A process for producing an eyelet for a biomedical electrode (e.g. an electrocardiogram (ECG) electrode) involves: hot pressing an electrically conductive thermoplastic or elastomeric resin to produce a film having a web of eyelets, each eyelet having a post protruding from a first face of the film and a flange at a second face of the film; applying a coating of a non-polarizable conductive material (e.g. a silver-containing material) on to a contact face of the flange; and, cutting the film to produce the eyelets separated from the web. Preferably, the process involves extrusion replication. A web of eyelets for biomedical electrodes has a film of an electrically conductive thermoplastic or elastomeric resin possessing a plurality of posts protruding from a first face of the film, and preferably a layer of a non-polarizable conductive material on a second face of the film. The process may be a one-step continuous process that is cheaper and simpler than current commercial processes.
