摘要:
Process and machine for manufacturing an auxiliary element for producing an outer wrap for covering a mattress, of the kind which contains a layer (3) of sponge rubber and a layer (4) of textile fibre joined to a covering fabric (5) comprising the steps of:
defibering and cutting off a material from the recovery of used covering outer wraps (6) of mattresses and/or waste of manufacturing new covering outer wraps (6) for mattresses, obtaining a size of pieces of sponge rubber in the defibered and cut off material (6a) contributing with a fluffy consistence; laying the defibered and cut off material (6a) as a blanket (11) forming a layer of fluffy material; depositing a thin layer of sponge rubber (12) on said blanket (11); depositing a layer of textile fibre (13) on said thin layer of sponge rubber (12); and consolidating by die cut or basting stitches a junction between said blanket (11), layer (12) and layer (13), obtaining an auxiliary element (14) which is handleable and can be thereafter joined to a covering fabric (15).

An automatic quilting machine (10) for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt (100) is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction. The sewing machine head (110) is mounted on a cross beam (16) which is aligned at the approximate center point of the metal frame on which the fabric (100) is stretched. The needle of the sewing machine head (110) can stitch a pattern into any location in the fabric (100) and the metal frame is moved in any direction relative to the fixed sewing machine head (110) in order to bring the desired stitch location on the fabric (100) into alignment with the sewing machine head (110). The pattern can be created through reading by a scanner (130) when then converts the pattern into machine readable language which is stored in a process controller (172). Alternatively, the pattern can be hand drawn on a monitor (140) by graphic systems such as a mouse (180) combined with computer aided design programs which provide graphic menus and through which the drawn pattern can be converted into machine readable language which is then stored in the memory of a process controller (172). The stored pattern can be subsequently stitched into the fabric (100) through commands from the process controller (172) which direct a remote control apparatus to move the table in the desired direction to create the pattern.

The sewing machine assembly comprises a base having a work surface (11) and a sewing machine including a sewing machine drive and a stitching needle assembly (380) for sewing materials disposed on the work surface. In order to facilitate the loading and unloading of thick materials, the stitching needle assembly (380) comprises a linkage (372) coupling the sewing needle (13) to the sewing machine drive for mowing the sewing needle to provide a desired stitching pattern and means (370) unconnected to the sewing machine drive for raising and lowering the sewing needle (13) in a vertical direction with respect to the work surface independently of the sewing machine drive.

Wire netting mats are used in many areas of fire, heat and sound-proofing technology. Wire netting is sewn to a mineral wool mat by means of a binding wire which is guided per seam in a backstitch in each case forming a loop through the mineral wool mat and the wire netting. In order to avoid the backstitched seams becoming undone during rough handling on building sites, i.e. to ensure that the wire netting and the mineral wool mat are permanently connected, according to the invention, when the backstitched seam has been sewn in the region of the lower and/or upper large surface of the mineral wool web the binding wire is mechanically deformed in steps so that the backstitched seam is prevented from becoming undone.

A modular material supply system (10) for an automated quilting machine (12) having a variety of fill material supply devices (14), a cover material tick magazine (16), a fill laminator (26), and optionally a digital printer (60). The system (10) is capable of selecting the desired cover (22) and fill materials (20) and supplying them continuously to a laminator (26) to form a layered material (58), which is then fed to the quilting machine (12). The flexibility of the modular system (10) reduces the need for system downtime to changeover component materials for producing different quilted products.

Sewing apparatus for stitching a side panel or a flange material to a top panel of a mattress sack. The sewing apparatus automatically pivots the mattress sack upon encountering a corner, and automatically positions the mattress sack for stitching along the next edge. In one embodiment, a pair of sleds (510, 512) is utilized to automatically guide the mattress sack through the sewing head (80) and to automatically position the mattress sack for proper pivoting. Other features include a detector (40a) for detecting when a corner has been reached to begin the pivoting at a fixed distance from the sewing machine to produce a properly rounded and symmetrical corner, and a correction wheel (30) to properly align the top panel with the side panel or underlying flange material. A further aspect includes a fabric flattener (90) for urging fill within the top panel toward a cut edge of the top panel.

摘要:
A method and apparatus for stitching a label to material, particularly to a quilted mattress panel, in which the material and the label are joined face side down rather than face side up. The label is held face side down with a clamp and a panel is held over the label by a clamp, and the two are joined by a sewing machine. The invention further includes a mechanism for activating the thread knife of the sewing machine at such a time that the bobbin thread only is cut. In a further aspect of the invention, a masking mechanism is provided for masking the electronic signals of the sewing machine that would otherwise cause the machine to reset at a normal needle height, so that a sewing operation can be stopped with a needle at a maximum clearance position. In a further aspect, pneumatic cylinders and linkage are provided for raising the needle and presser foot even further at the end of a stitching operation.
