Abstract: A wrapping machine for wrapping products is provided with a product diverter for producing package formats which are greater in width than the number of lanes which deliver product to the wrapper machine. A plurality of metering belts advance product from an infeed conveyor along a plurality of infeed lanes. The metering belts are independently driven so that product can be advanced in each lane independently of the product in the other lanes. The metering belts deliver product to accelerator belts which speed up the product to create a gap between successive products in a lane. A first flighted conveyor advances product from the accelerator belts to a plurality of pivotally mounted diverting gates, corresponding in number to the number of infeed lanes. Each of the diverting gates direct the product to one of a plurality of output lanes. The number of output lanes is equal to, less than, or greater than the number of infeed lanes.

Abstract: A method and apparatus for sharpening saw blades having planetary motion in transverse cutting as for multi-ply webs in stacks or log rolls wherein a saw blade is carried on a planetary arm moving through an orbit skewed relative to the path of travel of the product to be cut, the grinding system being mounted on the planetary arm and including an adjustment arm carrying grinding stones; the adjustment arm being pivoted to bring the stones in contact with the blade and indexed so as to compensate for blade wear.

Abstract: A method of controlling stack back pressure in folding apparatus incorporating sensing the bulk of a stack issuing from folding rolls, forming a signal corresponding to the sensed bulk, comparing the signal with a predetermined signal range and changing the size of an embossing nip gap or pressure whenever the signal is outside of the range.
