Forming apparatus comprising: - a forming carousel having a frame that rotates around a rotating axis and carries a plurality of forming units that are angularly spaced apart from one another around said rotating axis; - for each forming unit, a first half unit and a second half unit that are able to assume at least one closing position, wherein between said half units (22; 23) a compression force is generated that is suitable for forming an object, and at least one open position, wherein it is possible to introduce an object to be formed and expel a formed object, said half units (22; 23) being able to perform at least one reciprocal approaching movement to close the forming unit and a reciprocal distancing movement to open the forming unit, at least said first half unit being movable with respect to said frame; - for each first half unit, at least one movable auxiliary member connected to said first half unit by motion multiplying transmission means arranged such that an auxiliary movement of said auxiliary member by a certain amount is matched by a main movement of said first half unit by a larger amount; - for each first half unit, a first cam follower means associated with said auxiliary member, at each rotation of the carousel said first cam follower means being coupled with first cam means to command at least one first closing step of the forming unit with an approach of said first half unit to said second half unit caused by an auxiliary movement of said auxiliary member guided by said first cam means; - for each first half unit, a second cam follower means associated with said first half unit, at each rotation of the carousel said second cam follower means being coupled with second cam means to command at least a second closing step of the forming unit, in the presence of the compression force that is discharged at least partially onto said second cam means during said second closing step. - a forming carousel having a frame that rotates around a rotating axis and carries a plurality of forming units that are angularly spaced apart from one another around said rotating axis; - for each forming unit, a first half unit and a second half unit that are able to assume at least one closing position, wherein between said half units (22; 23) a compression force is generated that is suitable for forming an object, and at least one open position, wherein it is possible to introduce an object to be formed and expel a formed object, said half units (22; 23) being able to perform at least one reciprocal approaching movement to close the forming unit and a reciprocal distancing movement to open the forming unit, at least said first half unit being movable with respect to said frame; - for each first half unit, at least one movable auxiliary member connected to said first half unit by motion multiplying transmission means arranged such that an auxiliary movement of said auxiliary member by a certain amount is matched by a main movement of said first half unit by a larger amount; - for each first half unit, a first cam follower means associated with said auxiliary member, at each rotation of the carousel said first cam follower means being coupled with first cam means to command at least one first closing step of the forming unit with an approach of said first half unit to said second half unit caused by an auxiliary movement of said auxiliary member guided by said first cam means; - for each first half unit, a second cam follower means associated with said first half unit, at each rotation of the carousel said second cam follower means being coupled with second cam means to command at least a second closing step of the forming unit, in the presence of the compression force that is discharged at least partially onto said second cam means during said second closing step.
