Abstract: The present invention relates to a roof cladding element, which roof cladding element has been manufactured of profiled plate material and which roof cladding elements are adjacently and in succession mountable such that the edges of a roof cladding element will be placed a distance overlapping with the edges of adjacent roof cladding elements. The present invention also relates to a method for manufacturing roof cladding elements in which method a plate material in strip form is formed into profiled roof cladding element strip with a forming device and in which method a finished formed roof cladding element strip is cut with a cutting device at even intervals into roof cladding elements. Characteristic to a roof cladding element in accordance with the invention is the fact that to at least one corner of a roof cladding element a recess reaching at least partly under the lower surface of the part of the roof cladding element surrounding the corner has been formed.

Abstract: The objective of the invention is a roof cladding element with hidden fastening, which roof cladding element has been manufactured of plate material, and which roof cladding elements are adjacently and in succession mountable such that the edges of roof cladding elements will be placed a distance overlapping the edges of adjacent roof cladding elements, and which roof cladding element includes at least one step mainly transversal with the cladding, which step has at least one locking recess for locking a roof cladding element at least from one step to the next lower roof cladding element, and which roof cladding element includes at least one attaching shoulder placed at the upper edge of a roof cladding element for fastening of the upper edge of a roof cladding element to the fastening construction of the cladding and for tightening and locking of at least the locking recess next to the lower edge of a roof cladding element to the locking recess placed in the upper part of the next roof cladding element place

Abstract: An apparatus for manufacturing a roofing panel has been accomplished such that the desired panel version can be produced by altering the infeed point of the panel (6) on a feeding table (5). The apparatus can be utilized in the manufacture of roofing panels of various materials and with varied profile shapes.
