Abstract

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 …
