Abstract
Abstract The invention relates to web supply apparatus of the type wherein web is unwound alternately from each of two similar mobile roll stands each movable in the direction of its web roll axis between an unwind position usually in line with a web consuming machine and a loading position laterally offset from the path of the web. The two roll stands generally move on floor supported tracks between their loading and unwind positions and each is equipped with a portion of a web splicing device so constructed that, in the loading position a ready web roll having been picked up from the floor has its leading end so prepared and mounted that when the ready roll stand is moved to the unwind position, the ready web may be spliced automatically to the trailing end of the running web by the co-action of the two splicer halves mounted on the unwinding and ready roll stands.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
113 words
Apparatus adapted for splicing the leading end of a ready web from a roll supported on a first roll stand to the trailing end of a running web unwinding from a second roll stand characterized in that the stands are movable toward and away from each other in a direction generally parallel to the axes of the rolls and perpendicular to the direction of web travel, and further comprising means mounted on each roll stand for supporting the leading end of the ready web and cooperating means on each stand for bringing together the two web supporting means to form the splice when the two roll stands are in side by side relationship.
Claim 2
Dependent Claim
113 words
Apparatus adapted for splicing the leading end of a ready web from a roll supported on a first roll stand to the trailing end of a running web unwinding from a second roll stand characterized in that the stands are movable toward and away from each other in a direction generally parallel to the axes of the rolls and perpendicular to the direction of web travel, and further comprising means mounted on each roll stand for supporting the leading end of the ready web and cooperating means on each stand for bringing together the two web supporting means to form the splice when the two roll stands are in side by side relationship.
Claim 3
Dependent Claim
23 words
Apparatus according to claim 1 further characterized in that the web supporting means comprises a nip roller movably mounted on each roll stand.
Claim 4
Dependent Claim
40 words
Apparatus according to claim 2 further characterized in that the nip roller is perforated and further comprising means for connecting a vacuum source to the nip roller to hold the leading end of the web until the splice is formed.
Claim 5
Dependent Claim
64 words
Apparatus according to claim 2 further comprising mounting means at each nip end for each roller including a two armed pivoted lever having an arm on which the nip roller is supported and a buffer roller having one end mounted on the other arm of the lever and providing with the nip roller a path for the leading end portion of the ready web.
Claim 6
Dependent Claim
29 words
Apparatus according to claim 4 further characterized in that the path of the web trained over the buffer roller and nip roller passes adjacent the pivots of the levers.
Claim 7
Dependent Claim
28 words
Apparatus according to claim 4 further comprising a web severing blade mounted to engage the web generally in alignment with the axis of the pivots of the levers.
Claim 8
Dependent Claim

Apparatus according to claim 6 further comprising an elongated piston upon which the blade is directly mounted and a housing in which the piston is slidable in a direction perpendicular to the length of the piston.
Claim 9
Dependent Claim
71 words
Apparatus as defined in claim 1, further characterized in that each roll stand has a pair of adjustable web roll supportiNg arms, powered adjusting means for the arms, said coupling means including a chain loop passing adjacent the arms, means for driving the chain in one direction and couplers on the arms selectively operable for engaging the chain to cause the arms to move in a desired direction with the chain.
Claim 10
Dependent Claim
46 words
Apparatus according to claim 8 further characterized in that the chain is a roller chain passing through openings in the arms and the couplers comprise two fluid actuated pistons on each arm and a wedge coupled to each piston for locking the arm to the chain.
Claim 11
Dependent Claim
125 words
Apparatus for splicing the leading end of a ready web extending from a first roll to the trailing end of a running web unwinding from a second roll comprising a first roll stand for supporting the first roll, a second roll stand for supporting the second roll, said roll stands being movable toward and away from one another in a direction generally parallel to the axes of the rolls and perpendicular to the direction of web travel, a first splicer section carried by the first roll stand, a second splicer section carried by the second roll stand, means for bringing together the two splicer sections into cooperative engagement when the two roll stands are in side by side relationship so as to form the splice.
