Roll Wrappers

A Continuous Feed Roll Wrapper Wraps Up to 15 Rolls Per Minute Uses 54″ Diameter Pre-Printed Roll

The key to the Reichel & Drews Automatic Roll is an exclusive vacuum table system that eliminates the paper control problems that have plagued past wrapping systems. An innovative arrangement of driven belts feeds the wound roll and the use of vacuum technology provides superior cut paper control. The effects of wrap curl, twisting and skewing are all eliminated, providing a consistent, reliable feed of the wrap. Even air drafts from the surrounding area no longer affect the operation of the wrapping system.

  • Lowers Costs – Can handle up to a 54″ diameter preprinted roll instead of more expensive preprinted, precut wrap sheets
  • Minimizes waste by using jumbo rolls of preprinted wrap
  • Reduced labor costs and occupational injuries – Change out of the 54″ diameter rolls is less frequent than filling the magazine with precut sheets
  • Ensures superior sealing using a hot melt adhesive system
  • Results in tight, consistent wrapping

Description of Operation

A wound roll of roofing material is received onto the kick-off conveyor from the Customer’s winding operation. The pneumatically actuated conveyor is tilted, and the roll is deposited onto an approximately 15° decline section, and rolls onto a driven belt cradle section where it awaits delivery of a cut length of wrapping material.

A roll of wrapping material is unwound from a fabricated structural steel unwind stand. The wrapping material is extracted from the roll by a set of s-wrap pull rolls that are controlled by a dancer roll, and is fed to the cutting and application section.

The wrapping material is pulled from the unwind section by a set of pull rolls, past a photoelectric eyebar sensor. When the preprinted eyebar is sensed, the wrapping material is stopped and cut-to-length by a pneumatically actuated traversing knife assembly. During the cut-off operation, a bead of hot melt adhesive is applied to the trailing edge of the wrap by an adhesive application gun that is incorporated into the traversing knife assembly. At the same time, two dots of hot melt adhesive for wrap pick-up are applied to the leading edge of the wrap by individual application guns.

The cut length of wrapping material is fed onto a vacuum table with driven belts that are appropriately spaced to convey the wrap to the wound roll. The vacuum table ensures that the wrap has positive contact with the driven belts. The wound roll is spun in the driven belt cradle section, and the leading edge of the wrap is fed onto the roll. The roll is spun an appropriate amount of revolutions causing the wrap to fully encircle the roll and ensuring a tight, smooth wrap on the roll.

When the roll is fully wrapped the driven belt cradle section pneumatically pivots down and places the roll on the driven exit conveyor, which delivers it to the Customer’s palletizing operation.
