Downstacker | Corrugated Stacker

BW Papersystems is a leading manufacturer of corrugating, sheeting, and paper-converting machines, including the Downstacker, which is the last piece of equipment on the corrugated board production line. BW Papersystems aims to provide our customers with flat and perfectly stacked corrugated sheets at high run speeds, using operator friendly equipment.

Downstacker Product Features

BW Papersystems’ Downstackers provide outstanding stack quality and safe accessibility. With stacker top level access, lower-level access, and infeed access, safety is optimal.

Machines have flexibility on cam adjust infeed, and a knife outfeed section with shingling brushes. It is a key component of any dry end upgrade and can be installed in conjunction with any OEM dry end components.

Other features of our advanced machinery include:

  • Full-width V-Guide transport belts.
  • Continuous radius transport conveyor frame, preventing skewing of the shingle to the lift bay.
  • Patented speed switching allows clean load separation.
  • Reliable high-speed instant order change.
  • Exact sheet count.
  • Tail-based shingling.
  • Smooth acceleration and deceleration of the blue belt left bays.
  • High performance carbon fiber brushes.

Downstacker Applications

BW Papersystems’ expert team designed the Downstacker to fit a variety of applications and needs. Our machine provides superior stack quality for corrugated cardboard and other boards. The sync vac system at the entry of the Downstacker features precise control of the corrugated sheets. The machine is designed to handle microflutes down to .060” / 1.6mm.

Custom Machine Configurations

Every application is different, and BW Papersystems aims to meet every need. We provide custom catwalk configurations and conveyor lengths to ensure the machine fits with your existing production line. The Downstacker’s customization also ensures optimal operator use, safety, and efficiency. Multi-order stacking and dual discharge options are available as well.
