Abstract
Abstract An automatic paper splicer particularly for use in a high speed rotary press for automatically splicing one roll of paper to another roll of paper thereby to maintain a continuous web feed, which comprises an intermittently rotatable reel carrying a plurality of rolls of paper thereon and a paster head including at least one hook member engageable with an elastic member provided on the periphery of any one of the paper rolls so as to remove the elastic member therefrom thereby to permit adhesive material to be exposed. To this end, an arrangement of the paper roll provided with the elastic member is herein disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
457 words
An automatic paper splicer which comprises a reel carrying a plurality of rolls of paper freely rotatably mounted thereon, each of said paper rolls having the outermost layer of paper applied with adhesive material along the end extremity thereof which is in turn covered with a non-adhesive tape having an elastic member placed thereon so as to project outwardly of the peripheral surface of said paper roll, means for intermittently rotating said reel about its own axis of rotation thereby permitting any one of said paper rolls to be brought to an operative position, means for drawing the web of paper out from the paper roll in said operative position and for feeding the web of paper to utilization means, said rotating means being operated in response to reduction of the diameter of the paper roll being drawn by said drawing means thereby to replace it with the succeeding one of said paper rolls, a splicer head disposed adjacent to the periphery of said succeeding one of said paper rolls, said splicer head comprising a housing, a cylinder means for selectively bringing said housing between disengaged and engaged positions, said cylinder means including a hydraulic cylinder member having a hydraulically operated piston rod movable with respect thereto, said piston rod having one end pivotally connected with said housing so as to selectively bring the housing between the disengaged and engaged positions, an electromagnetic means housed in said housing and including a movable member for selectively projecting and retracting said movable member, means for supplying fluid medium to said cylinder means, means for intermitting the supply of fluid medium to said cylinder means only when said housing is brought to said engaged position adjacent to the periphery of said succeeding paper roll, wheeled carrier means provided with at least one hook member and supported by said movable member of said electromagnetic means such that, when said electromagnetic means is energized, said wheeled carrier means is projected toward the peripheral surface of said succeeding paper roll, a switch means for, when closed, de-energizing said electromagnetic means and concurrently for effecting the supply of fluid medium to the cylinder means so as to cause the housing to be brought to the dIsengaged position away from the peripheral surface of said succeeding paper roll, whereby said tape on the adhesive material coated on the outermost layer of paper of said succeeding paper roll is removed by the engagement between said hook member and said elastic member thereby to permit a leading portion of said outermost layer of paper of said succeeding paper roll to adhere to a trailing portion of the innermost layer of paper of the paper roll in the operative position so that a continuous web feed is ensured.

Dependent Claim
457 words
An automatic paper splicer which comprises a reel carrying a plurality of rolls of paper freely rotatably mounted thereon, each of said paper rolls having the outermost layer of paper applied with adhesive material along the end extremity thereof which is in turn covered with a non-adhesive tape having an elastic member placed thereon so as to project outwardly of the peripheral surface of said paper roll, means for intermittently rotating said reel about its own axis of rotation thereby permitting any one of said paper rolls to be brought to an operative position, means for drawing the web of paper out from the paper roll in said operative position and for feeding the web of paper to utilization means, said rotating means being operated in response to reduction of the diameter of the paper roll being drawn by said drawing means thereby to replace it with the succeeding one of said paper rolls, a splicer head disposed adjacent to the periphery of said succeeding one of said paper rolls, said splicer head comprising a housing, a cylinder means for selectively bringing said housing between disengaged and engaged positions, said cylinder means including a hydraulic cylinder member having a hydraulically operated piston rod movable with respect thereto, said piston rod having one end pivotally connected with said housing so as to selectively bring the housing between the disengaged and engaged positions, an electromagnetic means housed in said housing and including a movable member for selectively projecting and retracting said movable member, means for supplying fluid medium to said cylinder means, means for intermitting the supply of fluid medium to said cylinder means only when said housing is brought to said engaged position adjacent to the periphery of said succeeding paper roll, wheeled carrier means provided with at least one hook member and supported by said movable member of said electromagnetic means such that, when said electromagnetic means is energized, said wheeled carrier means is projected toward the peripheral surface of said succeeding paper roll, a switch means for, when closed, de-energizing said electromagnetic means and concurrently for effecting the supply of fluid medium to the cylinder means so as to cause the housing to be brought to the dIsengaged position away from the peripheral surface of said succeeding paper roll, whereby said tape on the adhesive material coated on the outermost layer of paper of said succeeding paper roll is removed by the engagement between said hook member and said elastic member thereby to permit a leading portion of said outermost layer of paper of said succeeding paper roll to adhere to a trailing portion of the innermost layer of paper of the paper roll in the operative position so that a continuous web feed is ensured.
Claim 3
Dependent Claim
41 words
An automatic paper splicer as claimed in claim 1, further comprising a scraper means for removing the elastic member, that has been engaged by the hook member, off from said hook member when said housing is returned to said disengaged position.
Claim 4
Dependent Claim
38 words
An automatic paper splicer as claimed in claim 1, wherein said switch means includes an actuator engageable with the elastic member, as said elastic member is hooked by said hook member, so as to close said switch means.
Claim 5
Dependent Claim
54 words
An automatic paper splicer as claimed in claim 1, wherein said hook member includes a needle portion oriented such that, when said movable member is in the projected position, the pointed end of said needle portion is ready to pierce a substantially intermediate portion of the elastic member with respect to the height thereof.
Claim 6
Dependent Claim
46 words
An automatic paper splicer as claimed in claim 1, wherein said hook member includes a needle portion oriented such that the longitudinal axis of said needle portion is in parallel relation to the tangent which touches a point on the periphery of the succeeding paper roll.
Claim 7
Dependent Claim
46 words
An automatic paper splicer as claimed in claim 1, further comprising a suspension system for cushioning either or all of the bouncing and rolling actions of the splicer head which may take place when said splicer head rolls over a rouch surface of the paper roll.
Claim 8
Dependent Claim
119 words
A roll of paper having a leading end portion of substantially V-shape located on the outermost layer of the paper of said paper roll, which comprises an adhesive tape having the both opposite surfaces coated with adhesive material and placed on the outer surface of said leading end portion along the V-shaped configuration, a flexible tape having only one surface coated with material having no affinity to the adhesive material employed and covering said adhesive tape with said coated surface of said flexible tape facing to said adhesive tape, and means connected with said flexible tape on the outer surface of the leading end portion of said paper roll for removing said flexible tape to expose the adhesive tape.
Claim 9
Dependent Claim
