Abstract
Abstract An automatic quilting machine for stitching together according to any programmed pattern a plain upper material, a lower material, elastic in the warp sense and optionally an intermediate batting, which provides that a certain drawing of the stitching paths consisting of a predetermined elementary pattern repeated a given number of times, can be alternated with another or more different drawings, each of which is formed also by a plurality of repetitions of a basic pattern. Two sets of knobs control the circuits of the machine and select the basic patterns and preset an associate counter which cooperates with an impulse generator for determining the number of said basic patterns to be repeated before changing over the subsequent drawing by means of a converter.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
An automatic multineedle quilting machine for obtaining any desired but repeated pattern of stitching paths, comprising a carriage adapted to move transversely, a first electric clutch controlling the transverse movement of the carriage, a first programming disk for operating said first electric clutch, a second electric clutch controlling the forward movement of the material to be quilted, and a second programming disk for operating said second electric clutch, said quilting machine further comprising an impulse generator and an associated third disk means to drive said third disk and said associated impulse generator; a computer means receiving the control signals of said first and second programming disks and adapted to count the impulses of said impulse generator; and a plurality of first and second selecting means and a converter means preset by said plurality of first selecting means for programming a succession of elementary patterns and said plurality of second selecting means for programming the number of each of said elementary patterns to be repeated, said converter means being operated by said computer means to commute the quilting path from one of said patterns to the subsequent one in said succession.
Claim 2
Dependent Claim
190 words
An automatic multineedle quilting machine for obtaining any desired but repeated pattern of stitching paths, comprising a carriage adapted to move transversely, a first electric clutch controlling the transverse movement of the carriage, a first programming disk for operating said first electric clutch, a second electric clutch controlling the forward movement of the material to be quilted, and a second programming disk for operating said second electric clutch, said quilting machine further comprising an impulse generator and an associated third disk means to drive said third disk and said associated impulse generator; a computer means receiving the control signals of said first and second programming disks and adapted to count the impulses of said impulse generator; and a plurality of first and second selecting means and a converter means preset by said plurality of first selecting means for programming a succession of elementary patterns and said plurality of second selecting means for programming the number of each of said elementary patterns to be repeated, said converter means being operated by said computer means to commute the quilting path from one of said patterns to the subsequent one in said succession.
Claim 3
Dependent Claim
45 words
The automatic quilting machine of claim 1, wherein said computer means operates said converter means when the count of said impulses in said computer means is equal to said number of repeated elementary patterns preset by that second selecting means corresponding to said elementary pattern.
Claim 4
Dependent Claim
26 words
The automatic quilting machine of claim 2, wherein said impulse generator sends to said computer means an impulse upon each complete revolution of said third disk.
Claim 5
Dependent Claim
27 words
The automatic quilting machine of claim 3, wherein said third disk makes one complete revolution during the quilting operation according to any one of said elementary patterns.
Claim 6
Dependent Claim
36 words
The automatic quilting machine of claim 2, wherein said impulse generator sends to said computer means an impulse upon each given angle of rotation of said third disk, which is a submultiple of one complete revolution.
Claim 7
Dependent Claim
31 words
The automatic quilting machine of claim 5, wherein said third disk rotates by an angle submultiple of one complete revolution during the quilting operation according to anyone of said elementary patterns.
Claim 8
Dependent Claim
39 words
The automatic quilting machine of claim 1, wherein each of said plurality of first selecting means has contacts inserted in the circuits of said computer means which receive the signals of said programming disks for operating said electric clutches.
Claim 9
Dependent Claim
31 words
The automatic quilting machine of claim 1, wherein one of said elementary patterns is a longitudinal rectilinear stitching corresponding to said first electric clutch disengaged and said second electric clutch engaged.
