Abstract
Abstract The free tail end of a roll of paper is secured to the underlying layer of the roll by spreading the fibers of the paper at a plurality of a predetermined independent and discrete locations, and thereafter allowing the spread fibers to interlock with each other. This tail tie arrangement is achieved by pressing a plurality of individual pins or teeth into the surface of the paper roll, adjacent to the free or tail end thereof, under a predetermined pressure. On release of the pressure on the pins the spread fibers in the successive layers will interlock with each other.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
126 words
The method of securing the free tail end of paper on a roll comprising engaging a portion of the surface of said tail end of paper with a plurality of individual pins, urging said pins against said paper towards the center of the roll to depress individual areas of the paper roll beneath said pins for several layers of paper, thereby to spread the fibers of said paper in said areas; thereafter removing said pins from engagement with said paper, whereby said spread fibers interlock to hold said layers of paper together; and wherein said pins are mounted on a roller and said engaging step includes the step of moving said roller along the surface of said roll parallel to the central axis of said roll.
Claim 2
Independent Claim
126 words
The method of securing the free tail end of paper on a roll comprising engaging a portion of the surface of said tail end of paper with a plurality of individual pins, urging said pins against said paper towards the center of the roll to depress individual areas of the paper roll beneath said pins for several layers of paper, thereby to spread the fibers of said paper in said areas; thereafter removing said pins from engagement with said paper, whereby said spread fibers interlock to hold said layers of paper together; and wherein said pins are mounted on a roller and said engaging step includes the step of moving said roller along the surface of said roll parallel to the central axis of said roll.
Claim 3
Dependent Claim
25 words
The method as defined in claim 1 wherein said urging step comprises pushing said pins generally radially inwardly toward the central axis of said roll.
Claim 4
Dependent Claim
25 words
The method as defined in claim 2 including the step of wetting said tail end of said roll prior to said engaging and urging steps.
Claim 5
Dependent Claim
101 words
Apparatus for securing the free tail end of paper on a roll thereof comprising means for supporting said paper roll in a predetermined position, a pressure head having a plurality of individual barbed pins mounted thereon for engaging said roll at said predetermined position, and means for moving said head, Under pressure, into and out of engagement with said roll whereby the fibers of said paper are spread by said pins when they are engaged with the roll and said fibers interlock when the pin pressure thereon is relieved, thereby to interlock the first several layers of paper on the roll.
Claim 6
Dependent Claim
101 words
Apparatus for securing the free tail end of paper on a roll thereof comprising means for supporting said paper roll in a predetermined position, a pressure head having a plurality of individual barbed pins mounted thereon for engaging said roll at said predetermined position, and means for moving said head, Under pressure, into and out of engagement with said roll whereby the fibers of said paper are spread by said pins when they are engaged with the roll and said fibers interlock when the pin pressure thereon is relieved, thereby to interlock the first several layers of paper on the roll.
Claim 7
Dependent Claim
26 words
The apparatus as defined in claim 4 wherein said pressure head comprises a roller having a plurality of said pins mounted thereon and extending radially therefrom.
Claim 8
Dependent Claim
24 words
The apparatus as defined in claim 5 including means for lightly moistening a portion of said roll prior to its engagement by said pins.
Claim 9
Dependent Claim
28 words
The apparatus as defined in claim 5 wherein said moving means comprised a double acting ram having an actuator rod, said roller being rotatably mounted on said rod.
Claim 10
Dependent Claim
46 words
The apparatus as defined in claim 7 including a frame, said ram being resiliently mounted on said frame for movement in the direction of its axis and perpendicular to said roll whereby the resilient mounting of the ram accommodates variations in the thickness of said roll.
Claim 11
Dependent Claim
24 words
The apparatus as defined in claim 8 wherein said ram is pivotally mounted in said frame for movement in a plane containing said roll.
Claim 12
Dependent Claim
15 words
The apparatus as defined in claim 9 wherein said pins are generally conical in shape.
Claim 13
Dependent Claim
169 words
Apparatus for securing the free tail end of paper on a roll thereof, said apparatus comprising a frame, means in said frame for supporting said paper roll in a predetermined position, a pressure head comprising a roller rotatably mounted on said frame and having a plurality of individual radially extending pins therefrom for engaging said roll at said predetermined position, means for moving said roller, under pressure, into and out of engagement with said roll, and means for moving said paper roll with respect to said roller in a direction parallel to the central axis of the roll and transverse to the axis of rotation of the roller whereby when said roller is engaged with the paper roll it rotates along the surface of the paper roll on said pins thereby to spread the fibers of the paper when the pins are engaged with the roll, said fibers interlocking when the pins are removed from the roll, thereby to interlock the first several layers of paper on the roll.
Claim 14
Dependent Claim
169 words
Apparatus for securing the free tail end of paper on a roll thereof, said apparatus comprising a frame, means in said frame for supporting said paper roll in a predetermined position, a pressure head comprising a roller rotatably mounted on said frame and having a plurality of individual radially extending pins therefrom for engaging said roll at said predetermined position, means for moving said roller, under pressure, into and out of engagement with said roll, and means for moving said paper roll with respect to said roller in a direction parallel to the central axis of the roll and transverse to the axis of rotation of the roller whereby when said roller is engaged with the paper roll it rotates along the surface of the paper roll on said pins thereby to spread the fibers of the paper when the pins are engaged with the roll, said fibers interlocking when the pins are removed from the roll, thereby to interlock the first several layers of paper on the roll.
