Drum lagging material and installation apparatus therefor

A device for installing a jointed insulating material on a machine， comprising two or more opposing elongated members (2， 3)， when the elongated members are pulled together， the elongated members are extended to a releasable position and the drum The installation apparatus provided on 25 is disclosed. Thermal insulation materials for use on driven cylindrical pulleys or drums for industrial machines are disclosed. When joining opposing ends of the insulating material， the insulating material is present along the cross-machine direction of each opposing end of the insulating material to join the opposing ends of the insulating material. (seaming element) 16 may be included. The insulating material may also include a coating that increases the coefficient of friction of the insulating material so that when the insulating material is installed on the drum， no additional adhesive is required to keep the insulating material on the perimeter of the drum during operation. Disclosed are lagging materials for use on a driven cylindrical pulley or drum for an industrial machine. A lagging material can comprise a seaming element along the cross-machine direction (CD) of each of the opposing ends of the lagging material for forming a seam for seaming opposing ends of a lagging material when brought together. A lagging material can also comprise coatings that increase the Coefficient of Friction of a lagging material when the lagging material is installed onto the drum such that no additional adhesive is required to keep the lagging on the drum circumference when in operation. Also described is an apparatus for installing an on machine seamable lagging including at least two opposed elongate members， such that when the elongate members are drawn together， the lagging material is stretched into a seamable position to be installed on the drum.
