a first linkage connected to the first tool operative to move the first tool linearly along a linear axis of the first tool; a second linkage connected to the first tool operative to rotate the first tool axially about the linear axis of the first tool; and a first actuator portion having an arcuate inclined, sloped path operative to engage the first linkage. ### Claim 2 (depends on 1) The system of claim 1, wherein the first tool is a mandrel. ### Claim 3 (depends on 1) The system of claim 1, wherein the first tool includes a heating element operative to heat a portion of the first tool. ### Claim 4 (depends on 1) The system of claim 1, wherein the system includes a positioning assembly having a plurality of dog members disposed radially about the linear axis of the first tool operative to slide radially and align a rotational axis of the tubular sheet product roll with the linear axis of the first tool. ### Claim 5 (depends on 2) The system of claim 2, wherein the mandrel is cylindrically shaped. ### Claim 6 (depends on 2) The system of claim 2, wherein the mandrel includes a flared portion. ### Claim 7 (depends on 1) The system of claim 1, wherein the system further comprises a second tool operative to define a second portion of the core of the tubular sheet product roll. ### Claim 8 (depends on 2) The system of claim 2, wherein the mandrel includes a rib portion. ### Claim 9 (depends on 2) The system of claim 2, wherein the mandrel includes a conical tip having a point offset from a linear axis of the mandrel. ### Claim 10 (depends on 9) The system of claim 9, wherein the conical tip includes a planar portion. ### Claim 11 (depends on 7) The system of claim 7, wherein a linear axis of second tool is aligned coaxially with the linear axis of the first tool. ### Claim 12 (depends on 7) The system of claim 7, wherein the system further comprises a third linkage connected to the second tool operative to move the second tool linearly along the linear axis of the second tool; and a fourth linkage connected to the second tool operative to rotate the second tool axially about the linear axis of the second tool. ### Claim 13 (depends on 2) The system of claim 2, wherein the mandrel includes an inner cavity operative to receive a fluid, the inner cavity communicative with a port operative to emit the fluid. ### Claim 14 (depends on 13) The system of claim 13, wherein the fluid includes an adhesive. ### Claim 15 (depends on 13) The system of claim 13, wherein the fluid includes polyethylene glycol. ### Claim 16 (depends on 1) The system of claim 1, wherein the first linkage comprises a roller configured to travel along the inclined, sloped path of the first actuator portion. ### Claim 17 (depends on 1) The system of claim 1, wherein the first actuator portion is stationary. ### Claim 18 A system for forming a core of a tubular sheet product roll comprising: a first tool operative to define a first portion of the core of the tubular sheet product roll; a first linkage connected to the first tool operative to move the first tool linearly along a linear axis of the first tool, wherein the first linkage includes a roller; a second linkage connected to the first tool operative to rotate the first tool axially about the linear axis of the first tool; and a first actuator portion having an inclined, sloped path operative to engage the roller of the first linkage. ### Claim 19 (depends on 18) The system of claim 18, further comprising a spring configured to assist in maintaining contact between the roller and the first actuator portion.
