Abstract
Abstract In the conveyor system disclosed a rod grasps the forward ends of sheets to be conveyed by means of clips articulated on the rod. The rod extends between two parallel endless belts to which it may be engaged and disengaged. When engaged clasps extending from the ends of the rod embrace the belts and grip the webs of the belts. The belts pass through tapered openings in respective warping blocks so as to be squeezed and allow an operator to fit the belts into the clasps. Respective 180* twists in the belts reverse the warping each increment of each belt undergoes during each successive passage through the respective warping blocks. The rod may grasp and draw both individual sheets and continuous sheets through a processing apparatus.

A system, as in claim 3, wherein said passage has a flat portion intercepting a frusto-conical portion.
Claim 8
Dependent Claim
54 words
A system as in claim 3, wherein said block means form a first interior surface for applying an edge restraining force when said belt passes through said block means and a second surface for applying a force transverse to the surface of said belt means when said belt means travels through said block means.
Claim 9
Dependent Claim
34 words
A system as in claim 1, wherein said abutment means forms a second gripping means having a tight fit across the surfaces of the belt means about the outer edge of said belt means.
Claim 10
Dependent Claim
12 words
A system as in claim 1, wherein said belt means is endless.
Claim 11
Dependent Claim
15 words
A system as in claim 7, wherein said belt means includes a single 180* twist.
Claim 12
Dependent Claim
32 words
A system as in claim 1, further comprising second belt means travelling parallel to said first belt means and second engagement means on said carrier means for engaging said second belt means.
Claim 13
Dependent Claim
30 words
A system as in claim 9, wherein said carrier means includes a rod extending between said engagement means and a plurality of clips for grasping the material to be conveyed.
Claim 14
Dependent Claim
