Abstract: A machine for folding, cutting, and stacking napkins is provided. The machine has a feeding station, at least one pair of folding rollers pivoting about horizontal rotational axes, a blade, and a pair of spacers having fingers configured to support the napkins stably downstream of the blade, with respect to a horizontal plane perpendicular to a direction of travel, the folding rollers being provided with circumferential slots for inserting the spacers.

Abstract: The feeding unit (10) comprises: support means (12) for rotatably supporting a first reel (R1) of two-layer tissue web and a second reel (R2) of two-layer tissue web about respective axes of rotation (x1, x2); cutting means (32, 42) for cutting the two layers (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use, the cutting means (32, 42) being configured to cut the two layers (L1_1, L2_1) of the tissue web (W1) along two cut lines spaced apart from each other in the longitudinal direction of the web (W1); joining means (44_1, 44_2) for joining each of the two layers (L1_2, L2_2) of the tissue web (W2) of the other reel (R2) of said first and second reels (R1, R2), and precisely of the new reel, to a respective layer (L1_1, L2_1) of the tissue web (W1) of the reel (R1) in use; and tissue web accumulation means (30) for accumulating a given amount of web (W1) downstream of the cutting means (32, 42) and the joining means (44_1, 44_2) so as to ensure the feeding of the machine with the tissue web (W1) while the portion of tissue web (W1) on which the cutting means (32, 42) and the joining means (44_1, 44_2) act is kept temporarily still to allow the cutting of the two layers (L1_1, L2_1) of the tissue web (W1) in use and the joining of the latter with the two layers (L2_2, L2_2) of the new tissue web (W2).
