Abstract
An embroidering machine includes a frame for holding a work piece, a sewing machine for making an embroidery on the work piece, a controller establishing an embroidering operation by moving the frame, under the sewing machine, horizontally and vertically in a common plane based on embroidering data, and establishing calculations, before initiation of the sewing machine operation, of a single time duration required for one single complete movement of the frame based on the embroidering data and a total time duration required for the embroidering operation as a sum of the single time durations, and an indicator for indicating the total time duration.
Claims4
An embroidering machine comprising:
- a frame for holding a work piece;
- a sewing machine for making an embroidery on the work piece;
- a controller for controlling an embroidery operation by determining movement of the frame, under the sewing machine, horizontally in two perpendicular directions in a common plane based on embroidering data, and performing calculations, before sewing machine operation is initiated, to determine the length of a single time duration required for one single complete movement of the frame based on the embroidering data and the length of a total time duration required for the embroidering operation corresponding to a sum of a plurality of separately calculated single time durations;
- a main motor for driving said sewing machine and driving means for varying a rotational speed of said main motor in accordance with a pitch between two adjacent needle locations;
- and
- an indicator for indicating the length of the total time duration.
