Abstract: The invention relates to a quilting machine for fabrics, including at least three pairs of drive rollers between which the fabric can pass, one pair of rollers being the master pair and the other pairs of rollers being the slave pairs, generating a sewing area and a post-sewing area. Each pair of rollers consists of two opposing rollers associated with a set of chains and sprockets allowing the rollers to rotate in opposite directions to one another. The machine also includes pneumatic cylinders, associated with the pairs of drive rollers, for varying the distance between paired rollers, stabiliser bars for maintaining paired rollers parallel to one another, a sewing head, and a controller for controlling all of the pairs of drive rollers and the sewing head independently, exerting tension on the fabric in the sewing and post-sewing areas.

Abstract: A sewing machine includes a bed, a needle plate, a needle bar, a needle bar swing mechanism, an optical detecting portion, and a control portion. The optical detecting portion is configured to optically detect a cord pressed by a presser foot, and to output data representing the cord. The control portion is configured to calculate a width of the cord based on the data output by the optical detecting portion, calculate a swing width of the needle bar based on the width of the cord, and cause the needle bar swing mechanism to swing the needle bar with the swing width.

Abstract: A sewing system is disclosed for facilitating the sewing together with a sewing machine ends of at least two webs that are held by a spooling machine. A substantially horizontal carriage rail is supported by a support mounting means in fixed relationship with the spooling machine and itself slidably supports a sewing carriage adapted to hold the sewing machine.

Abstract: An automatic panel cutting and edge seaming system includes a series of side edge cutting and seaming assemblies that receive a fabric material and trim and sew seams along the side edges of the fabric material to form a desired width panel. Puller rolls pull the material through the side edge cutting and seaming assemblies and feed the trimmed and seamed fabric material to a cross-cut sewing assembly. After a sufficient length of fabric material has been fed to form a desired size panel, the cross-cut sewing assembly is engaged to cut and seam the end of the panel.

Abstract: A seaming machine for seaming segments of sheet material to one another to form larger sheets includes a frame defining a sheet-receiving area and a pair of spaced seaming devices on opposed sides of the sheet-receiving area for respectively seaming opposed edges of the segments of sheet material to one another. The frame typically defines a table-receiving space for a table to support the sheet segments. The machine provides for the seaming of multiple sheet segments while the sheet segments remain atop the table or another work surface. Relative back and forth movement between the frame and work surface facilitate the process.

Abstract: The present invention relates to a method for producing a large sewn product, such as a mattress panel or a quilt, having two stitched seams created by a sewing device, moving transversely to the direction of feed, between two adjacently arranged sewn products. The material between said seams is subsequently cut by the sewing unit, located within the sewing device. The apparatus comprises a conveyor mechanism, a sewing device consisting of a sewing unit with at least two needles, a gripper box with grippers allocated to said needles, a tape-like element, a cutting element, and a storage mechanism. By guiding the sewing unit along a first guide means, and by guiding the gripper box along a second guide means, and synchronizing both, material can be cut and sewn on the rim without tension, thereby improving current methods by avoiding sewing inaccuracies and eliminating their subsequent remedies.

Abstract: In a quilting system, a support and cassette apparatus includes a support with a cassette movably connected with the support such that the cassette captures the support within the cassette. A carriage is attached to the cassette.

Abstract: An apparatus for stitching a fabric and/or attaching guide rings to the fabric for possible use in a covering for an architectural opening includes a lift bar to which a top edge of the fabric is connected so the fabric can hang into an underlying housing where a plurality of individually operated clamps are positioned. The clamps can manipulate the fabric as the lift bar is raised or lowered while horizontal tucks are formed in the fabric with a reciprocating tucker blade. A pair of traversing sewing machines are used to stitch a tuck and/or attach guide rings to the tuck in an automated operation.

Abstract: An apparatus for forming fabrics for use, by way of example, in coverings for architectural openings includes a system for handling single or multi-layered fabrics by suspending the fabric from a lift tower, threading the fabric through various clamp systems within a housing for the apparatus, and subsequently forming horizontal rows of hobbles, tunnels, and/or attached rings by gripping and releasing the fabric with a vacuum clamp, upper and lower clamps, and a tucker blade clamp while a reciprocating tucker blade forms horizontal tucks in the fabric. Hobbles can also be formed in one layer of the fabric through use of the vacuum clamp which gathers a portion of one layer of the fabric while the other layer is handled differently. In doing so, hobbles are formed between tucks in the fabric with the hobbles establishing a fabric resembling a Roman shade.

Abstract: A quilting machine has at least one needle and looper set for forming chain-stitched patterns on a thick multilayered material such as a mattress ticking, preferably a panel of the continuous web clamped stationary on a frame. The stitch forming elements are mounted on separate heads that move independently transversely relative to the panel on a bridge that moves longitudinally relative to the panel. The bridge is longitudinally moved by a servo and the heads are transversely moved on the bridge by separate linear servos. The needle and looper are each driven by a linear servo having an armature to which the element is directly fixed to reciprocate without intervening mechanical linkage assemblies. A controller drives the servos to chain-stitch patterns, differentially move the heads transversely to account for transverse needle deflection and to phase the needle and looper to compensate for longitudinal needle deflection.

The sewing machine allows a material to be sewn, which is retained retainer, to be easily mounted or removed.

Abstract: In a chain stitch sewing mechanism with a sewing head movable parallel to the sewn material plane, including a needle rod with a needle drive for reciprocating a thread carrying needle, a catcher drive for reciprocating a needle shaped thread catcher with an open catching hook. The needle and thread catcher have movement paths forming a sharp angle with one another whose apex lies beneath the sewn material plane and the needle and catcher being so controlled such that a loop formed by the withdrawal of the needle is caught by the thread catcher and pulled through the material. A thread puller on a movable thread arm is moved towards the thread catcher and cooperates with the thread catcher for deflecting the loop hanging off the thread catcher at an angle to the movement path of the thread catcher toward the side opposite to that of the hook opening.
