Abstract
Abstract A lead-in table for guiding a plurality of horizontally moving webs into at least two horizontally diverging paths toward subsequent processing machinery such as a cutoff knife. The table includes a first set of slats which receives the webs from a slitter-scorer and guides them to a second sequentially adjoining set of slats. The first set is pivotable about an end to provide clearance for indexing the slitter-scorer or for setup of the heads on the slitter-scorer. The second set of slats guides the webs to the cutoff knife. Selected ones of the slats of the second set are pivotable to form variable-width guides corresponding to selected widths of the webs to guide them along horizontally diverging paths to the vertically displaced cutting rolls of the cutoff knife.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
247 words
Web-guiding apparatus for supporting and guiding a plurality of parallel moving webs, whose widths vary from time to time, from a web-receiving end to a web-delivering end opposite said receiving end for guiding said webs along horizontally diverging paths, said apparatus comprising: a support member extending traversely to the path of travel of said webs between said receiving and delivering ends for supporting the same; said receiving end including a first set of transversely spaced slats pivotally attached substantially horizontally to said support member and extending therefrom toward the oncoming webs; said delivering end including a second set of transversely spaced slats pivotally attached to said support member and extending substantially horizontally therefrom in the opposite direction to said receiving end; first power-actuating means operatively connected to said receiving end for positioning said first set of slats from a web-guiding position to a nonweb-guiding position when the widths of said webs are varied; and second power-actuating means operatively connected to each of said slats of said second set for positioning discreet ones thereof to form a support, having a width corresponding substantially to the width of at least one of said webs, extending along a path diverging substantially horizontally from said support with respect to the other of said slats of said second set; whereby the positioning of said discreet ones of said slats guides at least one of said webs along a path diverging substantially horizontally from the path followed by the others of said webs.
Claim 2
Dependent Claim
247 words
Web-guiding apparatus for supporting and guiding a plurality of parallel moving webs, whose widths vary from time to time, from a web-receiving end to a web-delivering end opposite said receiving end for guiding said webs along horizontally diverging paths, said apparatus comprising: a support member extending traversely to the path of travel of said webs between said receiving and delivering ends for supporting the same; said receiving end including a first set of transversely spaced slats pivotally attached substantially horizontally to said support member and extending therefrom toward the oncoming webs; said delivering end including a second set of transversely spaced slats pivotally attached to said support member and extending substantially horizontally therefrom in the opposite direction to said receiving end; first power-actuating means operatively connected to said receiving end for positioning said first set of slats from a web-guiding position to a nonweb-guiding position when the widths of said webs are varied; and second power-actuating means operatively connected to each of said slats of said second set for positioning discreet ones thereof to form a support, having a width corresponding substantially to the width of at least one of said webs, extending along a path diverging substantially horizontally from said support with respect to the other of said slats of said second set; whereby the positioning of said discreet ones of said slats guides at least one of said webs along a path diverging substantially horizontally from the path followed by the others of said webs.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein the slats of said first and said second sets are interdigitally spaced along said supporting member.
Claim 4
Dependent Claim
30 words
The apparatus of claim 2 wherein said first power-actuating means is attached to said supporting member and is operative to pivot all of the slats of said first set simultaneously.
Claim 5
Dependent Claim
50 words
The apparatus of claim 3 wherein the second power-actuating means includes a fluid-operated cylinder for each slat of said second set each of which is selectively operable to pivot its associated slat to a preselected position, said cylinders being pivotally attached to said delivering end and to their respective slats.
Claim 6
Dependent Claim
60 words
The apparatus of claim 2 wherein said first power-actuating means is operable to pivot said first set of slats from a first web-guiding position to a substantially upright nonweb-guiding position and to a second web-guiding position in which the slats extend from said support member in the same direction as, and substantially parallel to, the slats in said second set.
Claim 7
Dependent Claim
57 words
The apparatus of claim 1 wherein said discreet ones of said slats are positionable to at least two paths diverging horizontally from said support member with respect to the others of said slats for guiding separate ones of said webs along at least two pAths diverging substantially horizontally from the path of the other of said webs.
Claim 8
Dependent Claim
73 words
The apparatus of claim 1 wherein said support member is substantially vertically adjustable to change the horizontal level of the path of travel of said webs to a position above or below the level at which said webs are received by said receiving end for decreasing the angle of divergence of said horizontally diverging paths with respect to a horizontal line thereby providing a maximum amount of support for each of said webs.
