Claim Text:
1. A cam-controlled core insertion device for a surface winder, said cam-controlled core insertion device comprising: a cam housing having a longitudinal axis disposed therethrough; a cam disposed within a first surface of said cam housing, said cam being disposed within said cam housing about said longitudinal axis; a fixed finger plate juxtaposed proximate to said cam housing and said cam and having a fixed finger fixably attached thereto, said fixed finger plate being fixably attached to a shaft disposed through said cam housing, said shaft being disposed coaxially about said longitudinal axis and being rotatable thereabout, said fixed finger having a fixed orientation relative to said longitudinal axis as said shaft rotates about said longitudinal axis, said fixed finger having an end distal from said fixable attachment to said fixed finger plate; a first cam follower cooperatively associated with said cam, said first cam follower having a finger shaft attached thereto, said finger shaft being disposed through said fixed finger plate and having a movable finger attached thereto, wherein said first cam follower orbits about said longitudinal axis while juxtaposed proximate to and in contacting engagement with said cam, said movable finger having an adjustable orientation relative to said longitudinal axis as said first cam follower orbits about said longitudinal axis, said movable finger having an end distal from said first cam follower; wherein said distal end of said movable finger and said distal end of said fixed finger are capable of forming a space therebetween for contacting engagement and containment of a core suitable for the convolute disposal of a web material thereabout; wherein said cam causes said movable finger to rotate toward said fixed finger when said first cam follower is disposed at a first orbital position relative to said longitudinal axis to engage said core between said distal end of said movable finger and said distal end of said fixed finger; and, wherein said cam causes said movable finger to rotate away from said fixed finger to disengage from said core when said first cam follower is disposed at a second orbital position relative to said longitudinal axis.
