Abstract

A spool of fabric is fed through a series of rollers where it is exposed to cutters which trim it to a predetermined width, shear cusp-shaped indentations at regular intervals on opposing edges of the fabric and form perforations between the apices of the cusp-shaped indentations. After the perforations are formed, the fabric is burst in the vicinity thereof, thereby forming a mattress panel which is then disposed upon a second spool. During the foregoing operations, the fabric is maintained in an unwrinkled position by means of angular grooves formed upon gripping rollers in contact with the fabric.

Claims

1. In a mattress panel cutter, the combination comprising:

a. a frame;

b. a spool journaled in the the frames and provided with a roll of fabric;

c. adjustable means depending from said frame for trimming said fabric to a predetermined width;

d. spool means journaled in said frame for receiving trimmed edges of said fabric;

e. reciprocable means depending from said frame for successively cutting cusp-shaped indentations in opposing edges of the fabric after it is trimmed by said trimming means;

f. reciprocable means depending from said frame for perforating said fabric between the apices of said cusp-shaped indentations;

g. reciprocable means depending from said frame for bursting said fabric in the vicinity of said perforations;

h. means depending from said frame for tensioning said fabric;

i. means depending from said frame for urging said fabric outwardly of the longitudinal axis of said frame;

j. a spool journaled in said frame for accumulating a roll of said fabric after it has been burst in the vicinity of said perforations.

2. In a device according to claim 1:

a. said means depending from said frame for urging said fabric outwardly of the longitudinal axis of the frame including at least one roller contactable with said fabric and provided with at least one helical groove formed upon the circumferential periphery of the roller;

b. the fabric being pressed into the groove when the roller is brought into contact with the fabric

3. In a device according to claim 1:

a. said fabric being fed through a plurality of rollers disposed in vertically spaced relation;

b. the said rollers being contactable with said fabric;

c. the upper of said rollers being provided with a plurality of helical grooves formed upon its circumferential periphery;

d. the fabric being pressed into said grooves when said upper of said rollers is brought into contact with the fabric.
