Abstract: A method and the associated apparatus for the removal of floor coverings are presented. The removal of floor coverings is achieved in that up to 24 grooves (21) with a width (b) of 3 mm to 10 mm and with a depth (t) of up to 40 mm are simultaneously milled into the floor covering (20) at spacings (a) of 5 mm to 30 mm. The ribs (22) occurring between the grooves (21) are then knocked off by simple means, such as hammers, chisels or picks. In a second operation, by means of the same apparatus, further grooves (21) are milled transversely thereto, so that only rectangular elevations remain which can be knocked off with ease.
Abstract: A floor sanding machine is proposed, which consists of a case body (11) and a plurality of sanding tools (30) arranged eccentrically in the case body (11). The axes of the tool shafts (31) rotate about the axis of a central shaft (12), and the sanding tools (30) rotate about the axis of the tool shaft. The construction consists essentially of a belt drive, of which the unilaterally grooved drive belt (3) is driven on the grooved side of the main drive pulley (2) and drives a gear mechanism (5). Also on the grooved side of the drive belt (3), a belt tensioner (6) ensures that the drive belt (3) is always under sufficient tension. The tools (4) are driven via the non-grooved side of the drive belt (3).
Abstract: A separating- and support element (20, 21) for milling drums (1) on milling machines for coarse, uneven surfaces of concrete or asphalt, or for the removal of street markings, in which in a tool holder (2), shafts (4) are positioned between two flanges (5) on a radius (x), and milling tools (3) mounted in a loosely rotatable manner are placed thereon. The number of the milling tools (3) to be used can be determined freely in accordance with the use and the size of the milling tools (3). On the shafts (4) and between the flanges (5), milling tools (3) and separating- and support elements (20, 21) are consequently mounted alternating in a freely determinable sequence. The separating- and support elements (20, 21) comprise the central tube (6), whereby the distance of the two middle points (a and a′) corresponds to the radius (x).
Abstract: A milling cutter composed of various disks joined together to form a unit is proposed. A tool disk 11 is fixedly joined to at least one supporting disk 12 at the side by soldering, gluing or welding. The inside diameter of the bore 15 of the tool disk 11 corresponds at least to the inside diameter of the bore 16 of the supporting disk 12.
