Abstract
Abstract An improved guide means for use in an apparatus for making a multi-ply cross-laid material. The apparatus includes one or more satellite rolls of web material carried by a rotatable carrier disposed about a mandrel on which a continuous carrier belt is helically wound. A web from the satellite rolls is cross-laid on the belt and a subsequent web is then applied to the cross-laid web in advance of a slitter which slits the cross-laid web to yield the multi-ply material. The guide means includes an initially angularly adjustable turning bar that is also remotely adjustable so that the turning bar is movable in a linear direction while maintaining the initial angular position. The guide means also includes an idler roller around which the web passes prior to reaching the turning bar to maintain the angle of the web approaching the turning bar constant regardless of the amount of web present on the satellite roll.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
In an apparatus for forming a multiple web product, the apparatus having a cylindrical mandrel, a carrier rotatable about the mandrel and journaling a supply roll of an elongated web material, with the axis of the supply roll being substantially parallel to the mandrel axis, an improved guide means adapted to turn the web material such that the web material may be helically wound around the mandrel, the guide means including: an adjustable turning bar means angularly positioned in a plane tangent to the outer surface of the mandrel, the bar means being positioned to turn the web material to approach the mandrel at a predetermined angle, the plane of the web material approaching the mandrel being substantially tangent to the outer surface of the mandrel at a point where the web material is wound around the mandrel; and an idler roller means interposed between the supply roll and the turning bar means, the idler roller means having its axis substantially parallel to the mandrel axis, with the idler roller means being adapted to position the web material such that the plane of the web material approaching the turning bar means is substantially constant regardless of the amount of web material on the supply roll.
Claim 2
Dependent Claim
205 words
In an apparatus for forming a multiple web product, the apparatus having a cylindrical mandrel, a carrier rotatable about the mandrel and journaling a supply roll of an elongated web material, with the axis of the supply roll being substantially parallel to the mandrel axis, an improved guide means adapted to turn the web material such that the web material may be helically wound around the mandrel, the guide means including: an adjustable turning bar means angularly positioned in a plane tangent to the outer surface of the mandrel, the bar means being positioned to turn the web material to approach the mandrel at a predetermined angle, the plane of the web material approaching the mandrel being substantially tangent to the outer surface of the mandrel at a point where the web material is wound around the mandrel; and an idler roller means interposed between the supply roll and the turning bar means, the idler roller means having its axis substantially parallel to the mandrel axis, with the idler roller means being adapted to position the web material such that the plane of the web material approaching the turning bar means is substantially constant regardless of the amount of web material on the supply roll.
Claim 3
Dependent Claim
68 words
The apparatus of claim 1 further characterized in that the turning bar means includes adjusting means for moving the turning bar means toward and away from the mandrel in the plane tangent to the outer surface of the mandrel in order to shift the point where the web material is would around the mandrel without changing said predetermined angle of approach of the web material to the mandrel.
Claim 4
Dependent Claim
52 words
The apparatus of claim 1 further characterized in that the turning bar means includes adjusting means for changing the angularity of the turning bar means in the plane tangent to the outer surface of the mandrel in order to change said predetermined angle of approach of the web material to the mandrel.
Claim 5
Dependent Claim
59 words
The apparatus of claim 1 further characterized in that the idler roller is spaced from the surface of the mandrel a distance approximately equal to the diameter of the turning bar means, whereby the plane of the web material approaching the turning bar means is substantially parallel to the plane of the web material leaving the turning bar means.
Claim 6
Dependent Claim
61 words
The apparatus of claim 4 further characterized in that the turning bar means includes an adjustment means being operable to vary the distance between the turning bar means and the mandrel such that the angular position of the turning bar means remains substantially constant and the planes of the web material approaching and leaving the turning bar means remain substantially constant.
Claim 7
Dependent Claim
113 words
The apparatus of claim 4 further characterized in that the adjustment means includes: first and second support means associated with opposite ends of the turning bar means, the support means each having a threaded traveling nut means associated therewith, each of the nut means operably engaging a rotatable threaded screw means, with the screw means being positively coupled such that the rotation of one of the screw means correspondingly rotates the other screw means to thereby move each of the nut means whereby each of the support means and the turning bar is movable in the longitudinal direction of the screw means; and a drive means operable to rotate the threaded screw means.
Claim 8
Dependent Claim
72 words
The apparatus of claim 6 further characterized in that one of the support means includes an elongated arm connected to one end portion of the turning bar means and one of the threaded traveling nut means, with the elongated arm being slidably supported by a guide means associated with the carrier, the arm being adjustable to vary its effective length, thereby to variably adjust the angular position of the turning bar means.
Claim 9
Dependent Claim
53 words
The apparatus of claim 7 further characterized in that the arm means includes: two sections having threaded portions in cooperative engagement, such that rotation of one section relative to the other varies the length of the arm; and a locking means to prohibit rotation of one of the sections relative to the other.
Claim 10
Dependent Claim
56 words
The apparatus of claim 6 further characterized in that the drive means includes a motor associated with the carrier, with the motor being coupled with one of the screw means, the motor being reversible to reversibly rotate the screw means whereby the turning bar means is movable in opposite directions relative to the idler bar means.
Claim 11
Dependent Claim
152 words
The apparatus of claim 1 further characterized in that the carrier journals a pair of supply rolls of elongated web material and the guide means includes an adjustable turning bar means and an idler roller means for each web of material, with both of said turning bar means including adjusting means for changing the angularity of the turning bar means in the plane tangent to the outer surface of the mandrel in order to change said predetermined angle of approach of the web material to the mandrel, and at least one of said turning bar means including further adjusting means for moving the turning bar means toward and away from the mandrel in the plane tangent to the outer surface of the mandrel in order to shift the point where the web material is wound around the mandrel without changing said predetermined angle of approach of the web material to the mandrel.
