Claim 3

A calender device for the surface treatment of elongated material passing between rollers exerting a pressure onto each other under the action of magnetic forces comprising in combination: a. a plurality of at least three rollers, each having a periphery of magnetizable material and means for supporting them for rotation in equal spaced-apart relation about their respective axes which are generally disposed in parallel; b. at least one calender backup or counter roller having a central axis disposed centrally relative to and in parallel with the axis of said rollers of magnetizable material, so as to essentially operatively engage peripherally therewith during treatment of material passing between said rollers of paragraph (a); c. first and second magnet means disposed adjacent each of said rollers of paragraph (a) and providing a generally concentric arrangement of said rollers and magnet means, anD exerting a magnetic attractive force to bias said first-mentioned rollers of paragraph (a) toward said counterroller of paragraph (b) and in a generally peripheral direction toward one another; and d. said magnet means of paragraph (c) disposed relative to said rollers of paragraph (a) so that a resultant of the component magnetic forces acting between said each of said rollers and said related magnet means lies in a plane passing through the axes of said respective rollers and said counterroller.

Claim 4

A calender device for the surface treatment of elongated material passing between rollers exerting a pressure onto each other under the action of magnetic forces comprising in combination: a. a plurality of at least three rollers, each having a periphery of magnetizable material and means for supporting them for rotation in equal spaced-apart relation about their respective axes which are generally disposed in parallel; b. at least one calender backup or counter roller having a central axis disposed centrally relative to and in parallel with the axis of said rollers of magnetizable material, so as to essentially operatively engage peripherally therewith during treatment of material passing between said rollers of paragraph (a); c. first and second magnet means disposed adjacent each of said rollers of paragraph (a) and providing a generally concentric arrangement of said rollers and magnet means, anD exerting a magnetic attractive force to bias said first-mentioned rollers of paragraph (a) toward said counterroller of paragraph (b) and in a generally peripheral direction toward one another; and d. said magnet means of paragraph (c) disposed relative to said rollers of paragraph (a) so that a resultant of the component magnetic forces acting between said each of said rollers and said related magnet means lies in a plane passing through the axes of said respective rollers and said counterroller.

Claim 5

A device according to claim 2 further including means for adjusting the distances of said rollers of paragraph (a) relative to said counterroller to better accommodate the particular thickness of the material to be treated.

Claim 6

A device according to claim 2 wherein said magnet means comprise nonrotating magnet bars having opposite pole faces and extending generally over the breadth of the calender device, and together with said rollers of paragraph (a) form a closed static system.

Claim 7

A device according to claim 4 wherein some of said magnet bars have a dividing slot between the opposite pole faces, and disposed generally opposite to each other for the passage of the material therethrough treatment, and the inner magnet field of each magnet bar acting across the dividing slots.

Claim 8

A device according to claim 2 wherein a plurality of counterrollers corresponding in number to at least the number of rollers of paragraph (a) are arranged in parallel within the space enclosed by said rollers of magnetizable material and said magnet means; and each counterroller being essentially in operative rotating peripheral contact with a corresponding roller of paragraph (a).

Claim 9

A calender device for the surface treatment of elongated material passing between calender rollers exerting a pressure onto each other under the action of magnetic forces comprising; a. a plurality of at least three rollers having outer peripheries of a magnetizable material and means for supporting said rollers in equally spaced-apart peripheric relation with the respective axes parallel and for relative rotation in the same direction; b. at least one counterroller having an axis disposed parallel to and at least generally between at least two of said axes of said rollers of paragraph (a), and with the periphery of said counterroller being essentially in operative rotating contact with at least one of said rollers of paragraph (a); c. magnet means exerting magnetic attractive forces upon said rollers of paragraph (a) so that a resultant of said magnet attractive component force between each roller of paragraph (a) and said related magnet means lies in a plane connecting the respective axis of at least one of said rollers of paragraph (a) and that of said counter roller.

Claim 10

A calender device for the surface treatment of elongated material passing between calender rollers exerting a pressure onto each other under the action of magnetic forces comprising; a. a plurality of at least three rollers having outer peripheries of a magnetizable material and means for supporting said rollers in equally spaced-apart peripheric relation with the respective axes parallel and for relative rotation in the same direction; b. at least one counterroller having an axis disposed parallel to and at least generally between at least two of said axes of said rollers of paragraph (a), and with the periphery of said counterroller being essentially in operative rotating contact with at least one of said rollers of paragraph (a); c. magnet means exerting magnetic attractive forces upon said rollers of paragraph (a) so that a resultant of said magnet attractive component force between each roller of paragraph (a) and said related magnet means lies in a plane connecting the respective axis of at least one of said rollers of paragraph (a) and that of said counter roller.

Claim 11

A device according to claim 7 wherein a plurality of counterrollers corresponding in number to at least the number of rollers of paragraph (a) are arranged in parallel within the space enclosed by said rollers of magnetizable material and said magnet means; and each counterroller being essentially in operative rotating peripheral contact with a corresponding roller of paragraph (a).
