Loading the die into the press with a pallet jack can be dangerous. During the process, the die could get damaged, or someone could get hurt due to a pinch point. A pre-roller can eliminate some of these risks because it will smoothly guide the die into position. The pre-roller stands rollers have a larger diameter and are wider than those of a conventional pre-roller. This increases the contact point between the die and the rollers for easier movement in and out of the press.
A pre-roller can also save additional time for production. With a conventional pre-roller, it takes four times as long to perform a die change, and it requires an additional operator. A pre-roller stand can significantly reduce that time, and it requires fewer operators. A stand is recommended when loading dies that weigh 2 tons or more, are over 1300mm wide, or if die travel is over 1250mm.
Models with 2 rows and 4 rows are available for varying press sizes and die weights.
