Abstract:
A stitch regulation apparatus and method includes a material manipulation device. A movement detection device is connected with the material manipulation device and the movement detection device transmits the speed of movement of the material manipulation device. A receiver device receives transmissions from the movement detection device and a programmable speed regulation device containing stitch parameters, that is connected with a sewing machine and the receiver device, such that the speed regulation device receives movement data from the receiver device and regulates the speed of a sewing machine relative to movement data so as to produce the programmed stitch parameters in material to be stitched.
Abstract:
A digitizer is operably coupled to a quilting machine controller, wherein an operator can input free hand or traced patterns for regulating operation of a sewing head. The digitizer can be an X-Y encoder wherein the encoder includes a transparent or translucent sensing zone which provides for the operator to input a pattern while simultaneously viewing a portion of a textile, which can itself include a pattern.
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 machine includes a transfer device that is adapted to move a work cloth, a sewing device that moves a needle bar up and down, an operation device that includes an operation member and that outputs an output signal in accordance with a tilting operation of the operation member, the output signal specifying a position where a unit stitch formed, a unit data generation device that generates unit data being data for forming the unit stitch, a sewing data generation device that generates sewing data in accordance with the output signal and the unit data, a transfer control device that causes the work cloth to be moved by driving the transfer device in accordance with the sewing data, and a sewing control device that causes the unit stitch to be sewn on the work cloth by driving the sewing device in accordance with the sewing data.
Abstract:
A sewing machine capable of sewing while a workpiece cloth is moved by a manual operation includes a needlebar having a lower end to which a sewing needle is attached, a needlebar driving mechanism vertically driving the needlebar via a main shaft, a presser foot pressing the workpiece cloth, an imaging device imaging at least an area of the workpiece cloth near to the sewing needle, a movement amount operating device obtaining by operation a movement amount of the workpiece cloth based on image data supplied from the imaging device, a setting device setting a stitch pitch on the workpiece cloth, a comparing device comparing the obtained movement amount of the workpiece cloth and the set stitch pitch, a cloth movement limiter limiting movement of the workpiece cloth by the manual operation, and a control device controlling the cloth movement limiter according to a result of comparison.
Abstract:
The present invention provides alternative scroll-type yarn feed attachments for tufting machines characterized by independent servo-motor control of sets of yarn feed rolls, and a software design system to facilitate use of the attachment to produce novel patterns and photo images.
Abstract:
A quilting apparatus for enabling a user to freely move a stack of fabric layers across a planar bed relative to an actuatable stitch head. The apparatus includes a motion detector which detects the movement of the stack and controls the actuation of the stitch head. Consequently, the apparatus functions to synchronize the delivery of stitch strokes by the head with the manually controlled movement of the quilt material stack. This frees the user to move the stack over a wide range of speeds, to start or stop movement at will, and to guide the stack in any direction across the planar bed.
Abstract:
A sewing machine of the invention stores width dimensions and the reference needle penetration position dimensions, which all can be changed for writing and reading, according to the type of presser foot, in a memory. Based on the needle penetration position and the reference needle penetration position which are determined when the seam allowance width is set, the sewing machine calculates a distance between the left or right end of the presser foot and the position where stitches are made, and shows it on the display as the seam allowance width. Therefore, sewing can be made regarding the distance from the left or right end of the presser foot to the place where stitching is made as a seam allowance width, just by aligning the edge of the work cloth with the left or right end of the presser foot.
