The invention relates to a conveyor device for accelerating a series of products. The conveyor device includes a feed device for supplying products at a feed velocity along a transport path in the direction of transport T.sub.1. By operating an acceleration device located downstream of the feed device, the products are lifted up and transferred to a transfer device, which delivers the product downstream at regular intervals and at a higher velocity. The feed device includes a stationary take-over plate, and the acceleration device includes grippers which move along a hypocycloid path. In this case, the grippers preferably move along an essentially triangular path with a path section situated parallel to the direction of transport. By way of the grippers, the product which has been placed on the take-over plate is lifted up at a low initial velocity and is then accelerated in the direction of transport. Then, the product is taken over by a transfer device at a defined position and the product is delivered downstream at regular intervals and at a high velocity. Preferably, with the aid of a photocell and control unit, the velocity of the feed device is adjusted during constant operation of the acceleration device and the transfer device.
