Abstract: A roll feed includes a base body, a first tube roll having a rolling surface and a first bearing shaft, wherein the base body is configured to support the first tube roll and the first bearing shaft. The first bearing shaft and the first tube roll are configured to be detachably connected to each other for a rotationally fixed connection, wherein the base body is configured such that the first tube roll can be removed from the base body in an axial direction, wherein the axial direction is substantially parallel to an axis of rotation of the first tube roll.

Abstract: A feeder for conveying a workpiece, in particular strip material, in a conveying direction, comprises at least one first pair of side support modules; a base support module arranged between the side support modules; and at least one conveying module; wherein the side support modules are detachably connected to the base support module transversely to the conveying direction to form a U-shaped support structure of the feeder along the conveying direction; wherein the conveying module is arranged on the support structure movably in the conveying direction.

Abstract: A method is proposed for the production of a form tool, particularly for the shaping of plate-shaped or web-shaped starting material containing fiber material, comprising at least one male mold part and female mold part which are provided with form surfaces and recesses for guiding heated gas or steam and the like to the form surfaces and with devices for clamping on an apparatus, and whose form surfaces are shaped and formed from a sheet metal material, particularly perforated sheet metal, wherein in order to prevent any reworking at the form surface it is provided that a tap model, which is constructed as a negative form of the corresponding part of an original model, is used for shaping the sheet metal forming the form surface of a tool half, both the female mold and the male mold of the form tool, and that the perforated sheet metal forming the form surface remains fixed on the tap model until the frame and the possibly necessary reinforcements are connected to its rear side, which is open at the top.
