WOVEN FABRIC-LIKE JACQUARD FABRIC FOR MATTRESS TICKING AND METHOD FOR KNITTING THE SAME
20180100254 · 2018-04-12 ·

A jacquard fabric for a mattress ticking to be used for a bedding mattress and a method for knitting this jacquard fabric are provided. The method is for producing a jacquard fabric for a mattress ticking using a double-sided needle selection circular knitting machine of a rib gating type by which an arbitrary pattern is created by means of computer-based needle selection on a cylinder side, an arbitrary pattern is also created by means of computer-based needle selection on a dial side, and an arbitrary knitting structure is made in an arbitrary part by combining the pattern obtained on the cylinder side with the pattern obtained on the dial side. As a result of employing an irregular twill pattern as a background knitting structure serving as a base, a stretchable fabric that has a soft texture, a tight knitting structure, and strength similar to that of woven fabric is obtained.

METHOD AND SYSTEM FOR MANAGING AND CONTROLLING THE FEEDING OF AT LEAST ONE THREAD TO A TEXTILE MACHINE AS A FUNCTION OF THE OPERATING STEP OF THE LATTER
20180038023 · 2018-02-08 · ·

Method and system for managing and controlling feeding of at least one thread to a textile machine as a function of the machine operating step in product production or thread processing, such production or processing providing for a succession of steps corresponding to obtaining product parts or treating thread. The thread fed to the machine by a feeder at constant tension and/or speed and/or controlled by a sensor which monitors sliding or inherent characteristic thereof such as tension, speed, diameter, quantity and color. The sensor and/or feeder being controlled by a setting controller. The setting controller receiving synchronization signals from the machine and detectingaccording to the latterthe operating steps and thus product or production status. The operation setting programmed as a function of operating steps. The machine generates a unique synchronization signal, for each operating step, independently from step length.

Yarn recovery device and yarn feed system comprising said device
09656830 · 2017-05-23 · ·

A yarn recovery device includes a support structure that can be associated upstream or downstream with a yarn feed device, a yarn entry eye and exit eye rigidly connected to the support structure; a drum rotatably associated with the support structure having a seat to accommodate the yarn operationally located between the entry eye and the exit eye; the drum being switchable between a deactivated configuration, in which the seat is substantially aligned with the entry eye and the exit eye and the path of the yarn is not diverted by the drum, and an activated configuration, in which the seat is misaligned in relation to the entry eye and the exit eye and the path of the yarn is diverted by the drum that winds the yarn round itself.

Stock-controlling method for a storage yarn feeder with rotary drum
09604817 · 2017-03-28 · ·

A yarn feeder is provided with a drum which is driven to rotate by a motor controlled by a control unit for drawing yarn from a reel and winding it upon itself in the shape of loops forming a stock. The control unit estimates the stock on the drum on the basis of an information indicative of the amount of yarn which is unwound from the drum upon request from a downstream machine, and of an information indicative of the amount of yarn which is wound on the drum, and retroactively controls the motor to substantially stabilize the stock on a reference value. The control unit also performs a parallel correction routine in which compares the stock with the reference value to estimate a stock status RES<REF_RES or RESREF_RES, wherein RES is the estimated stock and REF_RES is the reference value.

Method and device for storing yarn in order to feed thread without creating twisting thereof
09598261 · 2017-03-21 · ·

A method for supplying a thread to a textile machine without creating torsions thereof includes picking up the thread from a reel, winding it on a rotary drum driven by an electric motor thereof and supplying such thread to the textile machine, preferably at constant tension and/or quantity. The method provides for measuring the amount of thread leaving the rotary drum and the amount of thread wound thereon and intervening on the rotation of such drum so the amount of thread leaving the drum is equivalent to the amount loaded thereon to avoid the creation of torsion on the thread. A device for implementing such method is also disclosed.
