Abstract

Abstract A system is provided for improving frame adjustments of automatic embroidery machines. Groupings of holes are punched in an elongated tape corresponding to binary numbers. The tape is read by an electro-optical reader which converts the information on the tape to electrical pulses which, in turn, control a drive system for causing the embroidery frame to move predetermined discrete distances.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 202 words
A system for improving adjustments of automatically operated embroidery machines having a movable frame comprising: an elongated tape having a plurality of rows, each row having at least nine predetermined spaces, said tape being of a jacquard type, said spaces adapted to be selectively encoded forming intelligence means on said tape; a grouping of said intelligence means in each row corresponding to a binary number; means for reading said binary number from said tape; means for converting said binary number into electrical pulses; means for driving the frame of said embroidery machine in the direction and distance in response to said pulses for providing an embroidered stitch; said intelligence means including holes punched in said tape, the information contained on said tape is substantially equally divided into two sides, one side providing information for frame movement in the X-axis, and the other side providing information for frame movement in the Y-axis; each side of row having a separate group of holes for forming a separate binary number, the two sides adapted to be read substantially simultaneously whereby the combination of the two numbers dictate the angular direction and distance of the stitch, each side of said tape having at least nine spaces.
Claim 2
Independent Claim 202 words
A system for improving adjustments of automatically operated embroidery machines having a movable frame comprising: an elongated tape having a plurality of rows, each row having at least nine predetermined spaces, said tape being of a jacquard type, said spaces adapted to be selectively encoded forming intelligence means on said tape; a grouping of said intelligence means in each row corresponding to a binary number; means for reading said binary number from said tape; means for converting said binary number into electrical pulses; means for driving the frame of said embroidery machine in the direction and distance in response to said pulses for providing an embroidered stitch; said intelligence means including holes punched in said tape, the information contained on said tape is substantially equally divided into two sides, one side providing information for frame movement in the X-axis, and the other side providing information for frame movement in the Y-axis; each side of row having a separate group of holes for forming a separate binary number, the two sides adapted to be read substantially simultaneously whereby the combination of the two numbers dictate the angular direction and distance of the stitch, each side of said tape having at least nine spaces.
Claim 3
Dependent Claim 57 words
A system as set forth in claim 1, wherein for each row on a side, the holes are in either in odd spaces or even spaces, holes in odd spaces causing frame movement in one linear direction along one axis and holes in even spaces causing frame movement in the other linear direction along the same axis.
Claim 4
Independent Claim 187 words
A method for improving adjustments of automatic operating embroidery machines having a movable frame comprising the steps of: providing an elongated jacquard tape having a plurality of rows, each row having at least nine predetermined spaces; selectively encoding intelligence means in said spaces of said tape; assigning a binary number to the grouping of said intelligence means in each row; reading said binary number from said tape; converting said binary number into electrical pulses; driving the frame of said embroidery machine in the direction and distance in response to said pulses for providing an embroidered stitch; said intelligence means are holes punched in said tape; and further including the steps of: dividing said tape into two sides, one side providing information for frame movement in the X direction and the other side providing information for frame movement in the Y direction; providing separate groups of holes for forming a separate binary number on each side; reading the two sides substantially simultaneously, whereby the combination of the two numbers dictate the angular direction and distance of the stitch, each side of said tape having at least nine spaces.
Claim 5
Independent Claim 187 words
A method for improving adjustments of automatic operating embroidery machines having a movable frame comprising the steps of: providing an elongated jacquard tape having a plurality of rows, each row having at least nine predetermined spaces; selectively encoding intelligence means in said spaces of said tape; assigning a binary number to the grouping of said intelligence means in each row; reading said binary number from said tape; converting said binary number into electrical pulses; driving the frame of said embroidery machine in the direction and distance in response to said pulses for providing an embroidered stitch; said intelligence means are holes punched in said tape; and further including the steps of: dividing said tape into two sides, one side providing information for frame movement in the X direction and the other side providing information for frame movement in the Y direction; providing separate groups of holes for forming a separate binary number on each side; reading the two sides substantially simultaneously, whereby the combination of the two numbers dictate the angular direction and distance of the stitch, each side of said tape having at least nine spaces.
Claim 6
Dependent Claim 39 words
The method as set forth in claim 3, further including the step of providing odd spaces in each row for indicating frame movement in one direction and even spaces in each row for indicating movement in the other direction.
