Method of making a nonwoven web
Soft point bonded nonwoven webs, and methods of making the same, are described that utilize a pattern of small, discrete bond points in a sequent pattern that together form macro-elements. The macro-elements are themselves positioned and aligned within a pattern such that mechanical stretching operations on the point bonded nonwoven webs yields soft and bulky fabrics but with reduced incidence of tearing or rupturing of the individual bond points.
Method for producing a biodegradable nonwoven fabric
The present disclosure provides: a biodegradable nonwoven fabric for thermoforming, the biodegradable nonwoven fabric being composed of a fiber of a polylactic acid-based polymer, and having a basis weight of 20-300 g/m.sup.2, preferably, a biodegradable nonwoven fabric characterized by being composed of a long fiber of a polylactic acid polymer, having an MD-direction elongation of 50% or more at 120° C., and having an MD-direction dimensional change rate of ±4% or less at 80-140° C. as determined by thermomechanical analysis; a method for producing a molded body by using said biodegradable nonwoven fabric; and a method for molding a biodegradable beverage extraction container, the method being characterized in that the molded body has an MD-direction elongation change rate of 4% or less, as determined by thermomechanical analysis (TMA) under a load of 0.05 N/2 mm at 30-100° C.
Method and device for inductively heating a stator or armature of an electric machine
The invention relates to a method and a heating device (1c) for inductively heating a stator (2) or armature (3) of an electric machine, in particular before and during trickle impregnation thereof. In addition, the invention relates to an impregnating device (50) in which this heating device (1c) is integrated. According to the invention, it is provided that the heating takes place inductively by electromagnetic fields of different frequencies. For this purpose, it is provided in the case of the heating device (1c) that it has at least one electromagnetic inductor (18, 21, 24) which is disposed coaxially or axially parallel with respect to the longitudinal axis (7) of the stator (2) or armature (3) and which inductively heats said stator or armature, and that the at least one inductor (18, 21, 24) is designed to generate at least two electromagnetic fields of different frequencies.

TENTER-CLIP CARRIAGE FOR A CONVEYOR CHAIN ARRANGEMENT OF A STRETCHING SYSTEM AND AN ASSOCIATED STRETCHING SYSTEM
A tenter-clip carriage for a stretching system comprises a longitudinal direction (LR) and a transverse direction and a clip body having a clamping device. The tenter-clip carriage comprises fastening portions in order to fasten the tenter-clip carriage to a partial chain portion of a conveyor chain arrangement of the stretching system. The tenter-clip carriage comprises at least one stabilising roller or at least one stabilising sliding element. The at least one stabilising roller or the at least one stabilising sliding element is, by means of a guide device: a) held directly on the tenter-clip carriage; or b) held indirectly on the tenter-clip carriage via a pin that connects two chain segments of the partial chain portion of the conveyor chain arrangement to one another and, specifically, unaffected by the feed and drive forces acting on the tenter-clip carriage or the partial chain portion to move the tenter-clip carriage and/or the partial chain portion.
The at least one stabilising roller or the at least one stabilising sliding element can be adjusted perpendicularly or transversely to the longitudinal direction by a force accumulator or spring-force accumulator.
Garment Construction Techniques Using Mesh Material
Multiple garment construction techniques are provided. The first garment construction technique is a method of creating ruching in a mesh material. The second garment construction technique is a method to gather a mesh material to reduce the edge length or to provide a stretch mesh fabric. The third garment construction technique is a method of creating an adjustable strap suitable using a G-clasp element for use with garments of mesh material or other fashion fabrics.
