Abstract: A feeder system for feeding objects to object-carriers of a machine for processing the objects, in particular a printing machine, includes a reciprocating finger for pushing each object directly towards an object-carrier to place the object on the object-carrier; the finger being carried by a reciprocating carriage slidably mounted on a chassis and rotatably mounted on the carriage so that it can occupy at least an operational position in which it can push an object when it is moved and a retracted position in which it can avoid an object when it is moved.

Abstract: A feeder system for feeding objects to object-carriers of a machine for processing the objects, in particular a printing machine, said system including a reciprocating finger (11) for pushing each object (10) directly towards an object-carrier to place the object (10) on said object-carrier: said finger (11) is carried by a reciprocating carriage (12) slidably mounted on a chassis (13) and is rotatably mounted on said carriage (12) so that it can occupy at least an operational position in which it can push an object (10) when it is moved and a retracted position in which it can avoid an object (10) when it is moved.

Abstract: An installation for inspecting compact discs includes a transfer turntable rotatable stepwise about an axis and mobile along that axis on each step with a plurality of transfer units carried by the transfer turntable which alternately pick up and put down a compact disc to be inspected. A plurality of action stations at the periphery of the transfer turntable include a loading station, at least two inspection stations, at least one reject station and an offloading station.

Abstract: A machine for printing oval objects. The oval object has imparted to it a simple pivoting movement about an axis which is separate from the center of the radius of curvature of a section of the area of the object to be screenprinted upon. The printing screen which is attached to a printing or a screen support is moveable to correct simultaneously the distance between the screen and the rotation axis of the object. The printing machine is applicable to processes for decorating convex surfaces by screen printing, hot pressing, and dry offset printing.

Abstract: In this printing machine, which is of the type comprising a horizontal printing station and, in vertical alignment with the latter, an exchange station, there are two transfer arms which are disposed at 90.degree. relative to each other, one on each side of a rotation axis inclined at 45.degree. which is common to them, in a plane containing the latter, and which occupy alternately a vertical position at the exchange station and a horizontal position at the printing station, and the holding means equipping each of these transfer arms for grasping an object to be printed comprises at least one clamp the two branches of which are each provided at their free end with a jaw adapted to encircle at least partially, in conjunction with the jaw of the other one, an object of this kind.
