Abstract
Apparatus for sensing a double thickness of a sheet-like product being conveyed past the apparatus by a feed device comprises a roll positionable adjacent the feed device. The roll has a perimeter partially defining a gap in the path of movement of the product. A support structure supports the roll for rotation relative thereto and for movement away from the path. A sensor senses movement of said roll away from said path. A caliper member is supported adjacent to the support structure. The support structure is mounted for adjustment to a position in which the gap has a width which is greater than the thickness of the product and less than the thickness of two products in response to positioning the product between the support structure and the caliper member. An adjustable member is movable to hold the support structure in the position to which it is move in response to positioning of the product between the support structure and the caliper member.
