A sewing accessory, namely, a button anchor and attachment system, with a button head and an anchor part. The anchor part includes two prongs that are attached to each other and the button head at the back face of the button head. The button anchor is attached to a garment by using a button anchor hole-puncher tool to punch a hole through the garment, inserting the anchor part of the button anchor in a closed position through the hole, and then bending the two prongs of the anchor part apart into an open position. The button anchor hole-puncher tool has a small blade on the front end and a handle on the back end.

A method for realizing articles having a predetermined area and aesthetic appearance uses frames to each of which a portion of material having a prevalent flat extension can be removably hooked. The method includes stitching or punching operations and cutting operations implemented on each portion of material in a first station, a second station and a third station sequentially. Cutting operations are executed on a first portion of material hooked to a first frame in a third station, while stitching or punching operations are carried out on a second portion of material hooked to a second frame and punching or stitching operations are performed on a third portion hooked to a third frame situated in the first station in phased relation.

A cutting table for cutting out a fiber preform obtained by three-dimensional weaving and having two portions that are connected together by at least one zone of non-interlinking and that present outlines of different shapes, includes a tabletop provided with a recess for receiving one of the portions of the fiber preform to be cut out. The fiber preform is capable of laying flat in the access. The cutting table further includes sacrificial plates for interposing between the portions of the fiber preform for cutting out and for being fastened to the tabletop. The sacrificial plates are capable of covering partially the recess of the tabletop while being fastened to the tabletop. The cutting table also includes a cutting template configured to be pressed against a portion of the fiber preform that is positioned outside of the recess, and a device for applying compacting pressure against the cutting template.

Tensile strength in a width direction and a longitudinal direction is improved without damaging a ventilation characteristic. A perforated film is a perforated film provided with holes, each of the holes is arranged at an intersection of a plurality of virtual lines extending along a direction and a plurality of virtual lines extending along a direction, and the direction is different from the width direction and the longitudinal direction. The direction and the direction may be both inclined at an angle larger than 30 and smaller than 60 to the width direction.

A tool and method for forming a perforation through a fiber preform includes a first and second tool components. Coaxial holes of the first and second tool components receive a plunger assembly that is translatable along the coaxial holes to perforate the fiber preform. Opposing surfaces of the first and second tool components circumscribe respective holes and contact the fiber preform during the perforation process.

There is provided an automated bi-stable valve system. The system includes a bi-stable valve mechanism with bi-stable valves. Each of the bi-stable valves is configured to switch between a valve closed state and a valve open state. The system includes a control system coupled to the bi-stable valve mechanism and configured to operably control the bi-stable valve mechanism. The control system includes, (i) at least one traversable bridge apparatus, and (ii) a valve switch mechanism attached to the traversable bridge apparatus, and movable, via the traversable bridge apparatus, over the bi-stable valves. The valve switch mechanism is configured to switch the bi-stable valve(s) between the valve closed state and the valve open state, to allow for selective control of one or more adhesion zones on the bi-stable valve mechanism. The adhesion zone(s) correspond to adhesion area(s) on a surface of a material to be selectively picked up and placed.
