An embroidering position setting device and method of operation thereof for an embroidering sewing machine are described. The embroidering sewing machine is capable of storing pattern data in a memory for a plurality of embroidery patterns which can be selectively read out to operate a stitch forming device to form the stitches of a selected pattern or patterns on a cloth to be stitched. An embroidering frame has a cloth extended thereon to be embroidered and is connected to an X-Y drive mechanism, said cloth having a mark located at an optional position for representing a reference embroidering position of the cloth. Jog keys are selectively operated to operate said X-Y drive mechanism thereby to shift said embroidering frame so that said reference embroidering position mark of the cloth may be located at the position under said machine needle in vertical alignment therewith. The position register key is operated to store said position of the reference embroidering position mark in an embroidering position memory as the reference embroidering position data. This position of the reference embroidering position mark is indicated together with crossed lines on a display which is operative in response to operation of said position register key. A pattern selecting device is then operated to select at least one of the embroidery patterns from said pattern memory, said selected embroidery pattern being stored in a memory (RAM) and being simultaneously indicated on said display with the center thereof being located at the center of said crossed lines.

A sewing machine capable of embroidery stitching and a embroidery data producing device for the machine are formed so that optionally selectable data are provided for forming the stitches of unit patterns to be embroidered, for arranging the unit pattern in series along a linear outline forming a looped pattern, for setting the size and the number of the unit patterns, the space between the unit patterns in an arrangement thereof and the size of the looped pattern, and stitch forming means is operated under control of said given data to form the stitches of the unit patterns arranged along the linear outline.

Sewing machine capable of embroidery stitching, and embroidery data

An electropressing apparatus includes an electric motor driven through a motor driver circuit to operate a pressing ram through a rotational mechanism constructed to move the pressing ram in a vertical direction relative the workpiece. Various detecting and control arrangements are used to detect, memorize, set and change the following: an initial position of the pressing ram; an upper limit stop position of the pressing ram with respect to the workpiece; a lower limit stop position of the pressing ram immediately above the workpiece; a position at which the pressing ram starts to apply a pressure to the workpiece; and a terminal position at which the pressing ram stops to apply pressure to the workpiece.
