A feed device (1) for a conveyor system (10) for preforms (4) is described, which is designed to convey preforms (4) coming in an orderly manner from an upstream module (109) of the conveyor system (10) to a downstream module (1011) of the conveyor system (10), the feed device (1) comprising a first and a second conveyor belt (11; 12), wherein a conveying path for the preforms (4) is formed between a first belt section of the first conveyor belt (11) and a second belt section of the second conveyor belt (12), wherein the first and second conveyor belts (11; 12) are arranged in such a way that a lateral edge surface (110) of the first conveyor belt (11) and a lateral edge surface (120) of the second conveyor belt (12) form a support for a supporting ring (41) of a preform (4), wherein the support can be brought into engagement with the underside of the supporting ring (41) in such a way that an accumulation force is applied in the conveying direction (F) to the preform (4) located in the conveying path.
