A tool or apparatus for preparing a fabric reinforced flexible hose or fabric reinforced conveyor belt for splicing by removing or stripping the elastomeric material forming the hose or belt from the fabric cords. The tool includes a knife disposed transversely of the hose or belt and movable longitudinally thereof while engaged with and partially penetrating the hose or belt for stripping the elastomeric material from the fabric, thus leaving and exposing the longitudinal cords on the end of the hose or belt thereby enabling a splice to be made. The knife is adjustable toward and away from the hose or belt and moves in an arcuate path about a center of an arcuate supporting surface or anvil for the hose or belt. The knife is mounted on an elongated actuating handle to enable sufficient force to be exerted on the knife to strip the elastomeric material from the fabric.
A tool for preparing an elastomeric item having longitudinal, flexible reinforcing elements embedded therein for splicing by stripping the elastomeric material from the reinforcing elements and exposing them for connection with identical exposed reinforcing elements when forming a splice between adjacent ends of items to be spliced, said tool comprising a supporting surface on which an elastomeric item may be placed, a knife having a straight edge extending transversely of and generally parallel to the supporting surface and elastomeric item for engaging the elastomeric item, and means supporting the knife for adjustment toward the elastomeric item and for movement longitudinally of the elastomeric item while engaged with the elastomeric material for stripping the elastomeric material from the longitudinal reinforcing elements, said supporting surface being arcuately curved with the axis of curvature paralleling the knife edge, said means supporting the knife including a support arm pivoted to move about an axis coincident with the center of curvature of the arcuate supporting surface whereby the knife moves in an arcuate path concentric with the arcuate supporting surface.
A device for stripping elastomeric material from the longitudinal reinforcing cords in a flexible hose in order to prepare the end of a hose for splicing with an adjacent hose end, said device comprising an arcuate supporting surface for supportingly engaging the outer surface of a flattened end portion of the hose with the axis of curvature of the supporting surface being transverse in relation to the longitudinal axis of the hose, means securing the end portion of the hose in flattened relation to the arcuate surface to prevent longitudinal movement of the end portion of the hose, a knife supported transversely above the flattened end portion of the hose in opposed substantially parallel relationship to the arcuate surface, said knife having a length generally equal to the width of the supporting surface, arm means supporting the knife for swinging movement in an arcuate path concentric with the arcuate surface and means to adjust the knife in relation to the arcuate surface for penetrating the elastomeric material to a desired depth for stripping the elastomeric material without destruction of the longitudinal reinforcing cords.
A device for stripping elastomeric material from the longitudinal reinforcing cords in a flexible hose in order to prepare the end of a hose for splicing with an adjacent hose end, said device comprising an arcuate supporting surface for a flattened end portion of the hose, means securing the end portion of the hose in flattened relation to the arcuate surface to prevent longitudinal movement of the end portion of the hose, a knife supported transversely above the flattened end portion of the hose in opposed relationship to the arcuate surface, arm means supporting the knife for swinging movement in an arcuate path concentric with the arcuate surface and means to adjust the knife in relation to the arcuate surface for penetrating the elastomeric material to a desired depth for stripping the elastomeric material without destruction of the longitudinal reinforcing cords, said arm means supporting the knife including an elongated rigid handle structure having a hand grip at the outer end thereof for manual manipulation thereof, said arcuate surface being in the form of a cylinder with central end pintles defining the axis of support for the arm means and knife, said knife including a recessed surface adjacent the inner edge thereof to facilitate stripping of the elastomeric material, said adjustment means for the knife including a pair of screw threaded members on said handle and engaging the outer edge of the knife for moving the knife radially inwardly toward the center of the arcuate surface.
