Optimizing Knife and Anvil Set-Up on Horizontal Wrappers

Set-up procedures for knives and anvils can vary according to the make and model of the packaging machine, knife adjustment style, and other factors. There are, however, some general principles that make these adjustments more effective and efficient, reducing downtime and parts costs.

  • Knives ground on a diagonal, or bias–whether they have a zig zag or a straight cutting edge–require less pressure to cut so they are easier to set up and typically last longer.
  • Zig zag knives with smaller (more) teeth are also easier to set up and provide longer life.

Case Study: Packaging Material Cost Reduction

Project Goals

The corporate engineering department at a large, international company commenced a project to reduce material costs for a variety of products that are individually packaged on horizontal flow wrappers. Greener Corporation was invited to participate in a series of meetings that defined the project’s initial goals:material cost reduction_Greener Corporation

  • To reduce the cut-off length for each package by reducing the overall seal width, thus allowing the product envelope to remain unchanged.
  • To achieve material savings without degrading seal integrity or productivity levels.
  • To achieve a project payback period of twelve months or less.

Clearance and Pressure on Horizontal Wrappers: What’s the Difference?

Greener’s latest “Tech Bites” video explains how proper clearance and pressure adjustments optimize horizontal flow wrapper performance.

Clearance and pressure settings on horizontal flow wrappers are critical for achieving quality packages, minimizing downtime, and controlling costs. We’ve noticed that the differences between clearance and pressure, and the proper occasions to adjust each of them, are not always clear to those making these adjustments. Greener’s latest “Tech Bites” video and blog post differentiate the function and adjustment of clearance and pressure. Read more
