An apparatus for installation of a lagging material for a cylindrical pulley or drive roll or drum for an industrial machine selected from a papermaking machine, nonwovens manufacturing machinery, or a corrugator machine for the manufacture of corrugated packaging board, comprising: at least two opposed elongate members (2, 3), each elongate member being structured to be placed longitudinally along the cross-machine direction of a drum or drive roll or pulley surface over opposing sides of a seaming area of a lagging material, a plurality of tensioning members (8a, 8b, 8c) operably engaged with the opposed elongate members (2, 3) for drawing the opposed elongate members (2, 3) together in the machine direction along the surface of a drum or drive roll or pulley, characterized in that the apparatus further comprises a plurality of lagging material engagement members (4a, 4b, 4c, 5a, 5b, 5c) attached to each opposed elongate member (2, 3), wherein each lagging material engagement member (4a, 4b, 4c) on one elongate member is substantially laterally paired in the machine direction with an opposing lagging material engagement member (5a, 5b, 5c) on the opposing elongate member, wherein the tensioning members (8a, 8b, 8c) are positioned proximate to each of the paired lagging material engagement members (4a, 5a, 4b, 5b, 4c, 5c), such that the tensioning members place a direct pulling force on the respective paired lagging material engagement members (4a, 5a, 4b, 5b, 4c, 5c) when the tensioning members are operated to draw the elongated members (2, 3) together, wherein each lagging material engagement member (4a, 4b, 4c, 5a, 5b, 5c) is structured to engage the lagging material such that when the elongate members are drawn together, an elastic lagging material is stretched into a seamable position to be installed on the drum or drive roll or pulley surface. at least two opposed elongate members (2, 3), each elongate member being structured to be placed longitudinally along the cross-machine direction of a drum or drive roll or pulley surface over opposing sides of a seaming area of a lagging material, a plurality of tensioning members (8a, 8b, 8c) operably engaged with the opposed elongate members (2, 3) for drawing the opposed elongate members (2, 3) together in the machine direction along the surface of a drum or drive roll or pulley, characterized in that the apparatus further comprises a plurality of lagging material engagement members (4a, 4b, 4c, 5a, 5b, 5c) attached to each opposed elongate member (2, 3), wherein each lagging material engagement member (4a, 4b, 4c) on one elongate member is substantially laterally paired in the machine direction with an opposing lagging material engagement member (5a, 5b, 5c) on the opposing elongate member, wherein the tensioning members (8a, 8b, 8c) are positioned proximate to each of the paired lagging material engagement members (4a, 5a, 4b, 5b, 4c, 5c), such that the tensioning members place a direct pulling force on the respective paired lagging material engagement members (4a, 5a, 4b, 5b, 4c, 5c) when the tensioning members are operated to draw the elongated members (2, 3) together, wherein each lagging material engagement member (4a, 4b, 4c, 5a, 5b, 5c) is structured to engage the lagging material such that when the elongate members are drawn together, an elastic lagging material is stretched into a seamable position to be installed on the drum or drive roll or pulley surface.
