Machine for winding a fibrous mat on itself

A winder intended for compressing a fibrous mat 4 rolls the mat up on itself and wraps it so as to store it and transport it with a reduced bulk. The machine has two belts 1, 2 supported by two fixed rollers 9, 13 and two mobile rollers 14, 15. The tension of the belts and the position of the mobile rollers are managed by a computer. The winding speed and the admissible compression ratio without damaging the fibrous mat are better than with the winder of the prior art.

A thermal marking device for surfaces of binder-containing webs of mineral wool includes, mounted on a raisable and lowerable mounting frame, a roller which has on its periphery electrically heatable marking elements. The marking elements carry image panels, the marking sections of which take the form of letters, symbols, pictorial represenations etc. and project at least 5 mm beyond the surface of the image panel. Furthermore, the envelope curve of the surface of the marking sections corresponds substantially to the outer surface of an annular cylinder, the axis of which coincides with the axis with the axis of the roller. Furthermore, the marking device is equipped with heating elements, the heating output from which can be locally and variously adjusted. As a result, it is possible to produce homogeneous marked patterns by a suitably reduced or increased supply of energy at locations having need for heat output while creating non-homogeneous decomposition patterns. The intensity of decomposition is thereby graded. Both possibilities can be used to produce a pictorial representation or an inscription or other identification on the surface of a web of mineral wool which contains binder.

An installation for the continuous manufacture of differing mineral fiber products, wherein control parameters associated with each fiber product to be manufactured are changed when the production line is to be changed from the production of one product to that of another. For this purpose, the individual control parameters for a new product are first adjusted by hand by means of a reference value adjusting device in the course of a test cycle and thereby optimized. Control signals corresponding to the adjustments thus obtained for a respective fiber product are then stored in a fixed memory and are addressable by means of a common address. If production of the same product is subsequently to be resumed, the set of associated control signals is transferred from the fixed memory to a CPU, whereby the whole production line or an envisaged part of the production line is immediately converted to the new product. Manual correcting devices switchably connected to the CPU in place of the reference value adjustment devices permit fine adjustments to be carried out on the stored reference values as required by the circumstances in each individual case.
