Abstract
A conveyor chain for gripping and conveying paper material has a plurality of links hingedly connected to each other. At least one of the links has a grip arm having a first grip surface. The grip arm is movable back and forth relative to a second grip surface of the chain between a grip position for holding paper material and a retracted position for insertion of the paper material between the first and second grip surfaces. The links are molded of plastic material. The or each grip arm is an integrally molded portion of one of the links. A conveyor including such a chain is also described.

A conveyor chain for gripping and conveying paper material comprising a plurality of links directly hinged to each other, each of the links having a grip arm having a first grip surface, the grip arm being movable back and forth relative to a second grip surface of the chain between a grip position for holding paper material and a retracted position for insertion of the paper material between the first and second grip surfaces;
- wherein, at least if the grip arm is in the grip position, the first and second grip surfaces face in opposite directions for engaging opposite surfaces of the paper material;
- and
- wherein the links are mutually identical and molded of plastic material, the grip arm being an integrally molded portion of one of the links.
A conveyor chain for gripping and conveying paper material comprising a plurality of links hingedly connected to each other, at least one of the links having a grip arm having a first grip surface, the grip arm being movable back and forth relative to a second grip surface of the chain between a grip position for holding paper material and a retracted position for insertion of the paper material between the first and second grip surfaces;
- wherein at least if the grip arm is in the grip position, the first and second grip surfaces face in opposite directions for engaging opposite surfaces of the paper material;
- wherein the links are molded of plastic material, the grip arm being an integrally molded portion of one of the links;
- and
- wherein, at least a portion of the first grip surface or the second grip surface is constituted by a surface of a projection, which projects into a hole in the second grip surface or, respectively, first grip surface, if the grip arm is in the gripping position in absence of paper material held by the first and second grip surfaces.
A conveyor chain for gripping and conveying paper material comprising a plurality of links hingedly connected to each other, at least one of the links having a grip arm having a first grip surface, the grip arm being movable back and forth relative to a second grip surface of the chain between a grip position for holding paper material and a retracted position for insertion of the paper material between the first and second grip surfaces;
- wherein, at least if the grip arm is in the grip position, the first and second grip surfaces face in opposite directions for engaging opposite surfaces of the paper material;
- wherein the links are molded of plastic material, the grip arm being an integrally molded portion of one of the links;
- wherein at least all of the links each including a grip arm are mutually identical:
- and
- wherein hinged connections between successive ones of the links are formed by mutually engaging hook portions of the successive links.
A conveyor comprising:
- a conveyor chain for gripping and conveying paper material comprising a plurality of links directly hinged to each other, each of the links having a grip arm having a first grip surface, the grip arm being movable back and forth relative to a second grip surface of the chain between a grip position for holding paper material and a retracted position for insertion of the paper material between the first and second grip surfaces;
- wherein, at least if the grip arm is in the grip position, the first and second grip surfaces face in opposite directions for engaging opposite surfaces of the paper material;
- and
- wherein the links are mutually identical and molded of plastic material, the grip arm being an integrally molded portion of one of the links, and
- a chain support structure for supporting the chain in a configuration defining a chain path, the chain support structure and the chain being arranged for causing the grip arm to assume the grip position in a transport section of the chain path and to assume the retracted position in an inserting section of the chain path.
