Abstract
Abstract Improved textile fiber bale opening apparatus having a multiplicity of conveyor belts each of which is supported by two spaced rollers and is rotatable about the rollers in both, opposite directions; outwardly directed needle means on the surface of the conveyor belts adapted to penetrate a bale resting thereon; motive means to drive the conveyor belts; and control means at opposite ends of the total conveyor belt path operatively connected to the drive means, and operative in response to a bale reaching this path end, adapted to reverse the drive direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
A bale opening apparatus comprising a multiplicity of bale supporting, aligned, endless conveyor belts, each belt being of a size sufficient to support a bale; drive means for moving all of said conveyor belts in the same direction at the same time whereby transporting bales from a conveyor belt to the next adjacent conveyor belt; control means operatively connected to said drive means controlling the direction of movement of said conveyor belts and causing the direction of movement of said conveyor belts to periodically reverse and a multiplicity of needle means directed outwardly of each conveyor belt of a length sufficient to penetrate bales supported on said conveyor belts and of a thickness sufficient to resist breakage wherein said needles are inclined from normal to said conveyor belts and where the needle inclination is in the opposition directions on adjacent belts; whereby said outwardly directed needles pluck fibers from bales resting on said conveyor belts as said conveyor belts drive said bales therealong .
Claim 2
Dependent Claim
164 words
A bale opening apparatus comprising a multiplicity of bale supporting, aligned, endless conveyor belts, each belt being of a size sufficient to support a bale; drive means for moving all of said conveyor belts in the same direction at the same time whereby transporting bales from a conveyor belt to the next adjacent conveyor belt; control means operatively connected to said drive means controlling the direction of movement of said conveyor belts and causing the direction of movement of said conveyor belts to periodically reverse and a multiplicity of needle means directed outwardly of each conveyor belt of a length sufficient to penetrate bales supported on said conveyor belts and of a thickness sufficient to resist breakage wherein said needles are inclined from normal to said conveyor belts and where the needle inclination is in the opposition directions on adjacent belts; whereby said outwardly directed needles pluck fibers from bales resting on said conveyor belts as said conveyor belts drive said bales therealong .
Claim 3
Dependent Claim
62 words
The improVed apparatus claimed in claim 1, wherein said belts are each endlessly disposed about two spaced rollers at least one of which rollers is driven by said drive means and wherein said control means is activated in response to said bales moving laterally to the outward extremity of said conveyor belts to reverse the direction of movement of said conveyor belts.
Claim 4
Dependent Claim
20 words
The improved apparatus claimed in claim 1, wherein the needles of adjacent conveyor belts are spaced apart a different amount.
Claim 5
Dependent Claim
18 words
The improved apparatus claimed in claim 1, including means for variable controlling the speed of said conveyor belts.
Claim 6
Dependent Claim
39 words
The improved apparatus claimed in claim 1, including a fiber receiving belt disposed below said conveyor belts to receive fibers plucked from said bales and including further transport means to convey said plucked fibers to additional textile processing equipment.
Claim 7
Dependent Claim
16 words
Improved apparatus claimed in claim 1, including means for varying the distance between said conveyor belts.
