A system and process for unwinding materials in forming absorbent articles is described. The system includes an unwind device in association with a festoon. The festoon is for accumulating a determined length of material. The amount of material contained in the festoon is increased or decreased depending upon the rate at which a roll of material is unwound in relation to the rate at which the first material is fed into a downstream process.

An improved start gate for gravity-driven cars which is itself a gravity-driven compound pendulum. The pendulum includes a horizontal drop member rigidly connected at one end to a start post support rod which in turn supports a plurality of start posts. A trigger lever, when moved either directly or remotely, allows the drop member to fall as in a compound pendulum thereby rotating the start posts and allowing the cars to start. The embodiment teaches that the subsequent initial start post acceleration is approximately twice the car acceleration. The equations of motion are solved showing that the start posts are guaranteed not to interfere with car motion. A major advantage over prior art spring-loaded start gates is that the gate “slap” from stopping overly-forceful spring motion and the associated track jarring and car jostling is eliminated, thereby contributing substantially to a more smooth and fair start.
