Taped belt electronic component centering device

In an electronic component centering and guiding device for centering components on a conveyor, said centering device including a support base and a pair of juxtaposed, elongated blades suitable to be centered with respect to said conveyor and oriented in the direction of travel of said components on said conveyor, means for pivotally attaching a first end of each of said blades to said base the other end of said blades swingable apart in unison and in symmetric motion in opposition to means for biasing said blades into contact with a component, whereby said blades center said component by translating said component transversely to said direction of travel of said component, the improvement comprising:

• a driven rotatable cam for opening said blades before reception and pass-through of said components and for controlling the rate of closure of said blades onto said component and reopening during pass-through, said cam contacting at least one of said first ends of said blades.
