Abstract: A glass scoring device includes a scoring head assembly and a carriage each pivotally mounted about an axis. The carriage has a pair of spaced wheels biased toward a glass ribbon and a support member. The support member biases a cutting force against the scoring head assembly to score a glass ribbon. Irregularities in the glass ribbon thickness and/or eccentric conveyor rolls oscillates the carriage and scoring head assembly about the axis. Oscillatory movement of the carriage scoring head assembly cooperate to maintain a constant cutting force on the scoring head assembly.

Abstract: A double bay industrial saw having delivery mechanism to receive timber cants of substantial size selectively directed to either saw bay where a single source of power operates multiple saw systems respectively operable to produce different types of boards with different edge configurations simultaneously as selected and desired. The cantilever type of pairs of arbors at opposite sides of a central housing respectively support sets of cooperating saw blades on driven arbors separately driven and supported upon separate arbors, and chippers if required to form edge configurations are also mounted upon said arbors, whereby the saws produce finished cuts in the cants to form completed products at the delivery end of the machine. Various feed rollers and cooperating pressure rollers insure positive feeding of the cants to and through the sawing regions of the machine.

Abstract: Method of, and apparatus for, making books using the two-up, coming and going method in which halfblocks, two of which form a double book block, are moved in a single stream, alternate halfblocks being turned through 180.degree. as they move and the halfblocks being collated in pairs each pair containing a turned and an unturned halfblock.
