.~.~> Responsive to edge location to control spreader {4}
DEFINITION
Classification: 26/74
(under subclass 71) Cloth expanding structure including means responsive to a particular condition of the running length of cloth to control a cloth expanding operation; i.e., to modify, stop or start the operation or to prevent or correct improper operation.
(1) Note. Cloth pull to drive an element (even such a spreader element as specified in the the roller of subclasses 97 or 99+) in itself does not constitute operation control for this subclasses (74+). Compare, however, with subclass 77 indented hereunder (74+), in which cloth pull not only drives the spreader but, further, controls and adjusts the angle of the roller and thereby of the selvage position responsive to the selvage location.
