• clutch means connected to said knife means for periodically operating said knife means and cutting the web at predetermined portions thereof into sheets of predetermined length as the web is fed to said knife means, said belts being disposed to receive the sheets as the web is cut;
• stop means at said second position and disposed to engage the sheets at their edges as they reach said second position;
• sheet stacking means disposed at said second position and above said upper surfaces of said belt for receiving and holding the sheets in vertically stacked relation, said stacking means comprising a pair of vertically extending uprights mounted on said stop means, said uprights being adjustably mounted for movement toward and away from each other and for movement in the length direction of said belts, said stop means being adjustably mounted for movement in the lengthwise direction of said belts, and said stop means being mounted on a fame which is adjustably pivotable around an axis transverse to the length of said belts for tilting said uprights with respect to the vertical;
• feeding means at said second position for delivering the sheets to said sheet stacking means and beneath any sheets previously received by said sheet stacking means, said feeding means being disposed below said sheet stacking means.

Apparatus for cutting a web into separate sheets and stacking such sheet as the web is fed into said apparatus, said apparatus comprising;

• at least three relatively long and narrow, laterally spaced belts disposed in side-by-side relation with their lengths substantially parallel for transporting sheets from a first position to a second position;
• motor means connected to said belts for moving the upper surfaces of said belts in the direction from said first position to said second position;
• rotatable knife means at said first position for cutting the web;
• clutch means connected to said knife means for periodically operating said knife means and cutting the web at predetermined portions thereof into sheets of predetermined length as the web is fed to said knife means, said belts being disposed to receive the sheets as the web is cut;
• stop means at said second position and disposed to engage the sheets at their edges as they reach said second position, said stop means being adjustably mounted for movement in the lengthwise direction of said belts;
• sheet stacking means disposed at said second position and above said upper surfaces of said belt for receiving and holding the sheets in vertically stacked relation;
• feeding means at said second position for delivering the sheets to said sheet stacking means and beneath any sheets previously received by said sheet stacking means, said feeding means being disposed below said sheet stacking means and comprising a plurality of stripping finers secured to said stop means and extending between pairs of said belts for stripping sheets from said belts.
