Abstract: Automatic multi-function multi-needle sewing machine comprising upper sewing members (14) and lower sewing members (15) cooperating with each other so as to achieve stitches (18) on a simple or padded fabric (11), with or without lining. The machine comprises at least an auxiliary supporting bar (19) cooperating with the sewing members (14, 15) and a plurality of accessory elements (28, 28a, 30, 37, 47, 51, 70) able to be selectively associated with said supporting bar (19) by means of attachment means (50, 60) of a standardized type, said accessory elements (28, 28a, 30, 37, 47, 51, 70) being interchangeable with each other so as to achieve one or the other of at least the operations of multiple sewing, application of accessories, such as ribbons, trimmings, paillettes or strass, tapes, longitudinally or transversely to said fabric (11), or crimping.

Abstract: A device for applying an embroidery material onto a textile fabric including a device for feeding the textile material; an upper sewing organ having a needle bearing bar and a plurality of needles; a lower sewing organ selected from the group consisting of shuttles, rotary crochets and moving hooks cooperating with the upper organ. At least one pressure plate for compressing the material and having embroidery devices thereon and a drive for providing rotational motion to the embroidery devices, wherein the drive device includes a hole for each needle to pass through and a second hole for the embroidery material to pass through, and wherein the rotational motion is in a single direction so as to direct the second hole in a position that is in front of the needle to obtain stitches on the textile fabric and to fix the embroidery material.

Abstract: Multi-needle quilting knotted-stitch machine with lower stitching elements having rotating hooks, the machine comprising an inlet assembly for the controlled feed of the textile material (11) to be quilted, a stitching assembly including upper stitching elements (12) and lower stitching elements and an outlet assembly for the collection and possible measurement and cutting of the quilted product (19). The upper stitching elements including at least two parallel bars (13) arranged lengthwise and supporting, in a position separated lengthwise, the relative stitching needles (24), the lower stitching elements of rotating hooks (17) being organized in longitudinal rows mating with the position of the relative needle-carrier bar (13), the position of each needle (24) corresponding to the position of a respective rotating hook (17).

Abstract: A multi-needle chain stitch sewing machine with a thread thread severing system and method thereof for cutting needle threads between two isolated stitched patterns of a fabric. The multi-needle sewing machine includes a plurality of loopers and respective needles, a thread severing strip located in close proximity and transversely across each looper, and eccentric guides connected to the thread severing strip for extending the thread severing strip to cut the needle threads and for retracting the thread severing strip so that the thread severing strip does not contact the needle threads during the stitching operation.

Abstract: An electronically controlled multi-needle quilting machine including linking cylinder arranged between an eccentric integral with a rotating spindle and a lever, to drive in an oscillating motion a number of loopers which, in combination with a number of corresponding needles, perform stiching operations by double chain stitches on a layered material interposed between said members, said linking cylinder comprising a pneumatic cylinder controlled to change the extension of its rod during the various operational steps, whereby the link length is changed and the loopers may reach a position in which, by being provided with a blade they perform a cutting operation on thread of respective needle.

Abstract: A device for disabling and enabling one or more needles in a quilting machine, a multi-needle embroidery machine, or the like, is described.The device comprises a linear actuator (24) adapted to carry a needle (22) and to keep the latter, for a predetermined time, in a raised position relative to fabric (10) to be sewn.The device includes stitching yarn (44) return means (38) being actuated when needle (22) is disabled, in order to subject to a limited tension the portion of stitching yarn located between the disabled needle and the fabric to be sewn, to prevent the yarn from becoming tangled and from breaking.Furthermore, during the entire operating stage as mentioned above, the known yarn tensioning device (48) through which the stitching yarn is led before arriving at the needle, is disabled.

Abstract: In a quilting machine two or more series of stitches are applied to the product, the product to which stitches have already been applied being moved forward and/or backward, even over a considerable distance, while the exact superposition of the fabrics is maintained.One embodiment of the machine comprises cylindrical containers (10, 11), in which are disposed the rolls (8, 9) of fabric (2, 3) which are to be quilted. During the backward rotation the cloth is wound over the constant diameter of these containers and in this way the tension applied is also constant.In another embodiment, return or loose rollers (160, 170) are provided, which take up a portion of fabric (102, 103) already unwound.The process also permits continuous embroidery, even very complicated embroidery.

Abstract: An apparatus for controlling the transverse movement of a fabric supporting carriage in a quilting machine. The carriage is coupled to a d.c. electric motor by a rack and pinion arrangement and the motor is fed by width modulated current pulses having fixed amplitude under control of a programmable processing unit such as a microcomputer.

Abstract: An apparatus for controlling the movement of a fabric-supporting carriage in a quilting machine includes a slider integral with the carriage. The slider is housed within a rotatable member and provided with an element slidably inserted in a shaped groove. The groove is formed in a perforated wall fixed in the frame below a guide in which the slider is positioned. The perforation in the wall is coaxial with a shaft which is fixed to a gear, the shaft being integral with the rotatable member.

Abstract: At least one needle-bearing bar of a quilting machine is connected to a reciprocable shaft, a control device is operatively arranged selectively to engage and to disengage the needle-bearing bar from the shaft. The control device includes either two electromagnetic or a pneumatically operated cylinder. A timer can be provided to effect energization of the electromagnets or fluid delivery to and venting of the cylinder.
