ABSTRACT:
Apparatus is provided for the lineal measurement of continuous or stranded materials, such as cloth, otherwise transported past such apparatus. A gravity operated contact wheel is used to bias the materials into engagement with a measuring wheel, the rotation of which generates incremental distance pulses which are summed in a counter. An electric eye is used to detect the presence of materials to be measured so that a measurement count is held as a trailing edge of such materials departs from between the measuring roll and contact roll. The entire device may be supported on a support base which is in turn adapted to fit into a preformed opening or slot in the top surface of a work area such as a cloth cutting table. In such instance, the measuring device operates to measure cloth drawn across the table and in between the measuring and contact rolls. A display is provided to show the amount of cloth transported between the two rolls, with the entire device being bidirectional so that a user may advance or retract the cloth so as to obtain a selected or given length of cloth to be cut or otherwise processed. The counter operates in conjunction with cloth sensing to hold an accumulated measurement for a given segment of cloth whenever a trailing edge of such cloth segment is detected leaving from between the measuring and contact rolls.
