A folding machine includes a first folding roll with a series of the gripper assemblies and a series of tucker assemblies uniformly and alternately spaced to interact with a series of gripper and tucker assemblies of an adjacent second folding roll. The series of alternately spaced gripper and tucker assemblies interact to grip, carry, and release material in a manner so as to generate a folded stack of material, such as sheet material. Each of the gripper assemblies generally includes a rotatable blade, a shaft configured to rotate the blade, a spacer disposed between the blade and the shaft, and a bolt coupling the blade and the spacer to the shaft. A housing is configured with seals to retain lubricated bearings to provide rotation of the shaft of the gripper assembly and to prevent contamination of the bearings.

Plieuse comprenant un premier rouleau plieur muni d'une série de préhenseurs et d'une série de plieurs placés à intervalles réguliers en alternance avec une série de préhenseurs et une série de plieurs fixés au second rouleau plieur. Les préhenseurs et les plieurs en alternance travaillent de concert pour saisir, transporter et déposer le matériel de façon à obtenir une pile de matériel plié, comme des feuilles. Chaque assemblage de préhenseurs comprend généralement une lame rotative, un arbre qui fait tourner la lame, une cale placée entre la lame et l'arbre ainsi qu'un boulon qui retient la lame et la cale sur l'arbre. Les roulements lubrifiés qui permettent à l'arbre de tourner sont montés dans un carter muni de joints d'étanchéité qui empêche leur contamination.
