Abstract: Calipering the thickness of individual books during production, independent of caliper bounce due to elastic resiliency of the books. A caliper roller is held apart from an anvil roller while a book is positioned between the two rollers. The caliper roller then is moved toward the anvil roller with sufficient resilient force to cause an initial maximum compression of the book between the caliper elements, followed by rebound movement of the caliper roller. The initial movement of the caliper roller is coupled to a measuring element through a lost-motion connection, so that the measuring element is not affected by rebound movement of the caliper roller. Movement of the measuring element thus corresponds to the initial maximum compression of the book by the caliper roller, which in turn corresponds to the actual thickness of that book.

For quantitative recording of this interaction, an image is recorded of one edge of each of the monitoring levers of one lever pair, and of the distance between these edges. The distance is a function of the thickness of the pressed printed product.

Abstract: A gage for measuring the external threads of a threaded body has a segment housing formed from a housing body. The housing body has a generally U-shaped cross section with a bottom extending between a pair of opposite, upright sidewalls so that a channel with a longitudinal axis is defined. First and second gage segments are configured to engage the threads of the threaded body when the threaded body is positioned between the first and second segments and the first and second segments are closed together. The first gage segment is fixed to the housing body, and the second gage segment is received within the channel of the housing body.
