DEFINITION

Classification: 26/90

(under subclass 89) Spreader in which the series of edge-retaining members is (are) spaced connected about the periphery of a rotating annular member (usually, paried series about spaced peripheries of the member or about peripheries of spaced accompanying (disc) members) to retain the running length edge(s) of a fabric web to effect spreading during movement of the edge(s) about the peripheries.

SEE OR SEARCH THIS CLASS, SUBCLASS:

88, for edge-entraining-wheel spreader structure in which the selvage is continuously and uniterruptedly clamped for travel rather than at intervals by the traveling series of this subclass (90).

93+, and 96, for tenter chains of the clamp or hook series type, respectively, in which the course of the chain(s) may bring the series about the periphery of a sprocket or drum whereat fabric-edge spreading could possibly be effected. The chain of clamps or hooks are guided, but not connected about the rotating annulus, as in the instant subclass (90).
