摘要： The invention relates to a coil-transporting carriage with adjustable retaining arms and to a method for the reliable handling of metal coils of small external diameter, or of sleeves, on a coiler mandrel. The coil-transporting carriage has a vertically displaceable coil saddle for accommodating a coil or a sleeve, also has two retaining arms for stabilizing the coil or the sleeve, the retaining arms being arranged opposite one another on the coil saddle and being pivotable by means of rotary drives, and additionally has a second drive unit for moving the coil-transporting carriage. For pulling off from a coiler mandrel, the coil saddle is positioned against a coil located on the coiler mandrel and the retaining arms are pivoted onto the coil. For pushing onto a coiler mandrel, first a sleeve is placed on the coil saddle of the coil-transporting carriage and is thereby guided by the retaining arms.

摘要： An adjustment device for adjusting a roll in a roll support (13) of a roll stand includes a cylinder housing (2) that can be secured to a roll support (13), and a piston (1) guided to move translationally in and across the roll support. The position of the piston (1) can be determined via a travel measurement device (9) connected to a coupling rod (6) secured directly to the piston (1). The piston (1) has a guide element (3) extending from the piston head (4) into a bore in the roll rack and in the direction toward the travel measurement device (9). The coupling rod (6) is secured to the guide element (3). To reduce the sensitivity of the adjustment device to a tipping, the guide element (3) is guided in a guide opening (14) of the cylinder housing (2). A sliding guide (7) is provided for the coupling rod (6), which can be arranged on an end of a borehole (15) in the roll rack facing the travel measurement device (9).
