    摘要： Le mécanisme de percussion de cet appareil, comprenant un cylindre (1), un piston libre (6), une enclume (18), un porte-outil (19) dans lequel est disposé un faisceau d'aiguilles (21) dont les têtes (21a) sont destinées à être appliquées contre l'enclume (18), est monté coulissant dans un carter tubulaire (10) entre deux ressorts (20, 22) servant à isoler dynamiquement ce mécanisme de percussion de ce carter (10) et de la poignée (14) qui sert à le tenir. Le cylindre (1) est monté dans ce carter par une suspension constituée de deux joints annulaires (11) et ce cylindre est ajusté avec un jeu de manière que le centrage conféré par les joints (11) isole mécaniquement ce cylindre du carter et réduit la transmission des vibrations.

    摘要： For repairing the surface of a roller R the pad-welding machine has a support 5 equipped with a motor for rotating the roller and a welding electrode 12 with a flux nozzle 13. To remove the slag forming on the surface of the pad weld a multi-needle beating mechanism 34 is mounted in an inclined position on a carriage 25 which is driven to and fro in synchronism with the movement of the welding torch 12 by a motor 27 driving a pinion which engages a rack. The carriage 25 is supported by a rail 23 which is mounted on extension arms 22 attached to the support 5.
