    Abstract: In a singulation saw for sawing either substrates or wafers there is provided a pair of counter-rotating saw blades mounted for independent movement in a vertical direction for alternately engaging with a first substrate to be singulated. A transport system comprising a pair of substrate carriers reciprocates the first substrate under the pair of saw blades while alternate ones of the saw blades are engaged to cut the substrate. While the first substrate is being cut, the second or other substrate carrier sequentially unloads a cut substrate, loads a new uncut substrate and then moves the uncut substrate to a vision system for determining the position of the substrate relative to the second carrier and then positions the second carrier and its substrate in a standby position ready to be cut by the pair of saw blades that are cutting the first substrate. As the first cut substrate is moved to an unload position, the new uncut substrate is moved into a cutting position; thus, a minimum loss of cutting time is incurred and a minimum amount of cooling water is needed.

    Abstract: A paper cutter for achieving high speed cutting having a simplified structure since movement of a blade can be controlled by a linear motor. A low level of noise can also be realized since typical mechanical elements for transferring power are eliminated. The movable blade forms less than a fifty degree angle with respect to a blade edge of the stationary blade, in the direction of blade motion, so that locally concentrated wear it minimized. By using a rotary blade as a movable blade, paper can be cut in both directions by reciprocating the movable blade.
