摘要： The invention relates to a machine for chamfering pieces of hide, leather and synthetic materials of small thickness, in which all the operating machine members, and particularly the rotary cup-shaped blade, the feed roller for feeding the piece to be chamfered and the grinder to sharpen the cup-shaped blade are driven by independent power units. Said machine is also provided with means for the non volatile storage of working programs and for the automatic execution of diversified operating phases according to said programs, with the possibility of interrupting the program, enabling the manual operation of the operating members, and of restoring it after the manual operation.

摘要： A device to move the sharpening grinding wheels in a leather splitting machine close to and away from a cutting blade. The grinding wheels are rotatably supported on the end portions of respective arms the other ends of which are pivoted on a carriage. The carriage, slidably movable on guiding rods, through an actuator, moves the grinding wheels from a position in which the latter are engaged on the bevel of the cutting blade to a position in which they are not in contact with the blade. In order to bring the grinding wheels back to the operative position on the cutting blade bevel, spring means is provided between the carriage and a bar rigidly connected to the splitting machine.

摘要： Platform for introducing sheet materials, particularly in leather splitting machines and the like, consisting of a plate suitable to slide in a reciprocating manner on a fixed level disposed at the top of a bearing structure. Balls are interposed between said plate and the fixed level for the purpose of assisting the sliding of the plate itself which is also provided with a guide block that engages into a rectilinear guide obtained on said fixed level, two rows of balls being interposed therebetween. In addition, said plate is provided with means causing the automatic return of the same to its starting position.
