Abstract
Apparatus for dispensing fabric from a bolt in which the bolt is cradled in a loop of an endless belt and unwound by driving the belt. The length of fabric unwound is accurately measured by measuring the distance of belt travel, and provision is made for presetting the length of fabric to be unwound, manually starting the belt to unwind the fabric, automatically starting measurement of the length unwound when the leading end of the fabric passes a predetermined point, and automatically stopping the belt when the preset length has been measured. The fabric unwound from the belt is automatically folded, and presented for being cut.
Claims22
Apparatus for dispensing fabric from a bolt comprising an endless belt conveyor, means guiding the conveyor for travel in an endless path including an upwardly opening loop in which a bolt may be cradled with the bolt extending transversely of the conveyor, means for driving the conveyor to rotate a bolt cradled in the loop to unwind fabric from the bolt, said guiding means including a first and a second guide for establishing said loop, the conveyor travelling over the first guide, thence downwardly, upwardly and over the second guide, and said apparatus having means mounting said guides for relative movement toward and away from one another as the bolt rotates, said guides being relatively movable from one another as the bolt rotates to a horizontal position and toward one another as the bolt rotates away from horizontal position.
Apparatus comprising holder means for holding a bolt of fabric, means for receiving fabric withdrawn from said bolt, measuring means intermediate said holder means and said receiving means to measure the length of fabric drawn off said bolt past a reference line, said measuring means including photocell means disposed at said reference line, register means to indicate the length of fabric drawn past said reference line, said holder means comprising a plurality of rollers and an endless flexible belt trained about said rollers, said belt having a loop in an upper pass thereof for receiving said bolt of fabric and means for adjusting the position of one of said rollers to vary the configuration of said loop in said belt.
Apparatus comprising holder means for holding a bolt of fabric, means for receiving fabric withdrawn from said bolt, measuring means intermediate said holder means and said receiving means to measure the length of fabric drawn off said bolt past a reference line, said measuring means including photocell means disposed at said reference line, and register means to indicate the length of fabric drawn past said reference line, said means for receiving the withdrawn fabric comprising bin means having a pair of inwardly and upwardly inclined bottom sections terminating in a peak for facilitating the fabric's being folded over on itself in folds.
Apparatus for measuring lengths of fabric, comprising a holder for a bolt of fabric comprising a flexible endless belt trained about a plurality of rollers, said belt having an upper pass defining a loop for the reception of a bolt of fabric, a table for receiving fabric withdrawn from the bolt of fabric, means disposed along the length of said table for sensing the advance of a leading edge of the fabric past a reference line, measuring means for determining the length of the fabric drawn past said reference line, a length-indicating register operatively connected to said measuring means, bin means for receiving fabric which has passed said reference line, said endless belt being trained over a pair of upper rollers, one of said upper rollers being movable toward and away from the other roller to adjust the depth of the loop of the belt between said rollers to accommodate tumbling motion of a bolt of fabric supported therein.
