Abstract: The invention relates to an articulation (1) for damping vibrations between an inner mechanical element and an outer mechanical element, comprising a rigid inner reinforcement (2), a rigid outer reinforcement (3), and a ring (4) made of at least one vibration damping elastomer material, which ring radially extends around the axial direction (X) between the inner reinforcement (2) and the outer reinforcement (3). The invention is characterized in that the first side flank (41) of the ring (4) comprises a first ring portion (51, 52) defined by a first surface (411, 412) and a second ring portion (53, 54) defined by a second surface (413, 414), which are diametrically opposed in relation to the axial direction (X) and which have, in the axial direction (X), respectively a first axial elevation (X1, X2) and a second axial elevation (X3, X4), which is higher than the first axial elevation (X1, X2).

Abstract: Is hereby provided an apparatus for batch cutting shingles, the apparatus comprising a table including a carriage module for receiving a plurality of shingle sheets thereon; and a power pack module supported by the table and operatively connected to a cutting module including at least two cutting blades mounted on a support arm, the two cutting blades being disposed at an angle thereof and adapted to simultaneously cut the plurality of shingle sheets to produce a plurality of shingle caps. A method of billing shingles cuttings with an apparatus for batch cutting shingle sheets and a method of cutting bundles of sheaves is also provided.

Abstract: An apparatus for removing shingles and shingle fasteners from a roof. The apparatus comprises a frame and a driver unit coupled to the frame, the driver unit including at least one motor. The apparatus also comprises a stripping unit coupled to the frame. The stripping unit is adapted to lift shingles off from a roof and to extract shingle fasteners out of the roof as the apparatus moves on the roof. The apparatus further comprises a pair of cutters coupled to the driver unit, the driver unit being operative to drive the pair of cutters. The pair of cutters is adapted to cut shingles lifted off from the roof by the stripping unit to produce a strip of shingle material, the strip of shingle material including at least a portion of a first shingle connected to at least a portion of a second shingle by at least one shingle fastener extracted out of the roof by the stripping unit.

Abstract: An apparatus for removing shingles and shingle fasteners from a roof. The apparatus comprises a frame and a driver unit coupled to the frame, the driver unit including at least one motor. The apparatus also comprises a stripping unit coupled to the driver unit, the driver unit being operative to alternately move the stripping unit between two positions. The stripping unit is adapted to lift shingles off from a roof and to extract shingle fasteners out of the roof as the stripping unit alternately moves between the two positions and the apparatus moves on the roof. The apparatus further comprises a pair of cutters coupled to the driver unit, the driver unit being operative to drive the pair of cutters.
