摘要:
A fiber structure manufacturing apparatus including: an accumulation portion that accumulates a material containing a resin and a fiber in air to generate a fiber web; a transport portion that transports the generated fiber web in a transport direction; and a heating and pressurizing portion that pressurizes the transported fiber web with a heated lower flat plate and an upper flat plate to melt the resin, in which a liquid absorbent having a first region where pressurization by the heating and pressurizing portion is performed the predetermined number of times and a second region where the pressurization is performed more than a predetermined number of times is formed by alternately repeating transport at a predetermined pitch shorter than a length of the flat plate in the transport direction by the transport portion and the pressurization.

The present invention relates to a porous support (20) intended to be removably positioned on a top side (11b) of a perforated plate (11) of a table (10) of a vacuum hold down device (1), the perforated plate having a bottom side (11a) connected to a vacuum system (13) for producing reduced pressure on the bottom side, wherein the porous support includes a perforated tray (21) provided on one side (21a) with outer reliefs (23) and on the other side (21b) with a blade penetrable porous structure (22) fixed thereon. The invention further relates to a vacuum hold down device (1) including such a support. The invention also relates to a process for replacing a first porous support by a second porous support in such a device.

A partially separated fiber bundle includes separation-processed sections, each divided into a plurality of bundles of at least three bundles, and not-separation-processed sections, that are alternately formed along the lengthwise direction of a fiber bundle that comprises a plurality of single fibers. The partially separated fiber bundle is characterized in that, at any width-direction cross-section taken along the lengthwise direction thereof, a rate of single fibers contained in a region at which adjacent divided fiber bundles are joined by a not-separation-processed part is 67% or less relative to the total single fibers in the width-direction cross-section.

A method including: providing a portion of double cloth including a first layer joined to a second layer, the layers being joined by a two-dimensional distribution of joining threads obtained by weaving; detaching the first layer from the second layer along an edge zone of the double cloth, to define on the first layer a band in which the first layer is separated from the second layer; cutting the band of the first layer, so that the second layer exhibits a projecting strip which projects with respect to a free edge of the first layer; arranging a further portion of fabric in contact with the second layer; joining the further portion of fabric to the second layer by a joining line arranged along the projecting strip; after the step of joining, turning the further portion of fabric, to move the further portion of fabric away from the second layer.

An ultrasonic device for cutting a meltable or fusible textile web and simultaneously welding or heat-sealing the cut edges is provided. A cutting knife works together with an anvil by means of a wedge-shaped cutter. The cutting knife or the anvil is connected with an ultrasonic transmitter. The cutting knife varies in cross section along the length of the cutter. The cutting knife and/or the anvil are/is adjustable in such a way that, in each case, the cross section of the cutting knife which is suitable for a determined thickness of the textile web is used.

A towel cloth drawing-out device comprises a pair of working tables facing each other with a gap therebetween, a towel cloth drawing unit for drawing out the towel cloth from the towel material to hang the same in the gap, a towel cloth clamp member which is provided in the gap and is able to reciprocate in the drawing direction of the towel cloth, a driving unit for reciprocating the towel cloth clamp member and a vertical wall which is provided on the side of one of the working tables, the working table being disposed on the drawing side of the towel cloth, for clamping the same between the towel cloth clamp member and itself. As a result, it is possible to automatically continue the cutting operation of towel cloth by successively drawing out the towel material without substantially stopping the cutting operation even if the towel material has a weave error in the length of uniformly woven portions therein since it can be drawn out long enough to be easily found and removed later so that it is possible to remarkably improve productivity and operability in a towel sewing factory.

A guide for use in cutting carpet and a method of joining two portions of cut carpet in edge-to-edge relationship has a base formed as a lower portion and an upper portion interengaged through a longitudinal slideway and presenting an upper ramp surface. The upper portion has a longitudinal channel along which a knife blade can pass to cut a carpet portion laid on the ramp. The lower portion has a vertical wall vertically below the channel and against which the cut edge of first carpet portion is located to abut during cutting of the second carpet portion on the ramp so that when the guide is removed the two cut edges will fall into edge-to-edge abutment for joining together.
