ABSTRACT:
A spool or warp beam for warp threads comprising an elongated tubular drum having circular steel brackets threadedly connected at the ends. The brackets are outwardly formed to provide a peripherally threaded section. A light alloy flange is provided with a circular cavity having a threaded periphery which turns upon the peripherally threaded section to interconnect the flange and bracket. The diameters of the threaded section and the cavity are designed to provide a shrink fit upon assembly. The coefficients of expansion of the bracket and flange materials are chosen to neutralize the shrinkage effect upon elevating the temperature of the assembly approximately 100.degree. centigrade.
