A multi-purpose calender having latterly spaced frames mounting four superposed calender rolls with their axes of rotation extending horizontally and three rolls offset relative to a vertical plane. Two outer rolls are provided with two coactive inner rolls intermediate the outer rolls. A first inner roll is mounted with an axis of rotation fixed in a vertical and in a horizontal plane. The frames have slot guides therein mounting beating housings and the bearings therein of the three other rolls adjustably shiftable and crossable independently along respective inclined planes.

Multi-purpose calendar

A method and charging apparatus for feeding successively individual strips of a deformable material to a calender for calendering under pressure between at least two rotatably driven calender rolls. The strips are produced from a strand of an elongated mass of deformable material provided from an extruder or rolling mill which is then cut into individual strips transported to a roller conveyor which positions them in a common plane successively at a selected or determined position extending transversely of the roller conveyor rollers in a direction parallel to the length direction of the calender rolls. An intermittently actuated pivotable belt conveyor having laterally spaced endless belts disposed below the roller conveyor and each aligned in a plane with a respective space between next-adjacent rollers of the roller conveyor lifts the individual strips off the roller conveyor to a higher level and advances the individual strips along a planar feed path at fight angles to the path in which the strips are advanced into position transversely of the roller conveyor and inclined toward the calender rolls and delivers them to the calender individually by discharging them successively off a pivot end of the belt conveyor disposed adjacent the feed nip of the calender. The individual strips are delivered extending uniformly parallel lengthwise with the gap between the calender rolls into which they are drawn for producing uniform calender products. The belt conveyor endless belts have free ends intermittently cyclically lifted above the level of the roller conveyor and lowered synchronously by a lever mechanism actuated by an intermittently energized fluid powered cylinder for cyclically effecting lifting a free end of the endless belts upon a detector detecting that an individual strip is in proper position on the roller conveyor for delivery to the calender along the inclined feed path and restoring the belt conveyor to a lowered position below the level of the roller conveyor when an individual strip has been discharged to feed the calender rolls. In the lowered position the belt conveyor is in readiness for delivery of a next sucessive strip to the calender to be calendered.
