When manufacturing hygiene papers, the traditional method of cutting the parent roll into smaller widths with an offline re-winder can limit the potential to increase the speed and efficiency of the paper machine. The reel spools may not return to the machine quickly enough, leading to unnecessary costs from extra handling and cleaning of spools or the disposal of butt rolls, which requires additional staff.

Each Trim-Jet™ H solution can be customized to include edge trimming and/or single or multiple slitting of hygiene grades needed for all your production sets. When automated, the slitting and edge trimming stations will precisely and repeatedly position each roll width as configured in the user-friendly interface. Each created production set can be saved and recalled, easing production changeovers and minimizing downtime for adjustments.

Features

• Cut trims as small as 20mm (0.75”) and up to 150mm (6”) or higher
• The system can eliminate the need to wind butt rolls by returning the unwanted product directly to the pulper
• Can handle and convey trims using compressed air or a blower fan
• Stainless steel construction
• Diamond cutting nozzles for reliable jets and long-life

Advantages

• Provides consistent airborne dust-free slitting
• Eliminates edge defects that may lead to sheet breaks at the reel or offline winder/slitter
• Can effectively trim an oscillating sheet to produce a high-quality fixed-edge

ROI

• The system reduces or eliminates the need for offline slitting converting processes
• It reduces manpower requirements
• Increased machine speed
• Sheet breaks caused by cracked edges are minimized
• Butt roll handling and bottom spool broke cleaning are eliminated

A paper edge-trimming system can be a crucial step in the paper-making process, as it allows for the removal of poor quality or cracked edges and uneven edge moisture, as well as the production of steady and precise web widths at any point along your online or offline processes. Additionally, the waste generated during the trimming process can be efficiently returned directly to the nearest pulper or remote broke chest, minimizing waste and maximizing resource utilization.

An edge trim unit is a highly effective solution for creating a high-quality and fixed edge in the cross-machine direction, overcoming the challenges posed by the sideways-moving web. By utilizing the Trim-Jet™ P edge trim unit, you can wind rolls with a perfect edge and prevent coating materials from seeping through gaps, thereby avoiding contamination on the other side of the sheet or its backing during coater application. Furthermore, the Trim-Jet™ P paper edge-trimming system maintains a fixed edge through calender and supercalender, reducing heat stress on the roll cover and eliminating uneven sheet edge caliper.

Features | Paper Edge-Trimming System

• Edge trim paper as small as 15mm (0.6”) and up to 150mm (6”) or higher
• Can handle and convey paper edge trims using compressed air or a blower fan
• Stainless steel construction
• Diamond cutting nozzles for reliable jets and long-life
• Can be installed where ropes are present

Advantages | Paper Edge-Trimming System

• Able to engage into any sheet edge quality to initiate any pre-set trim removal width
• Can effectively trim an oscillating sheet to produce a high-quality fixed-edge
• Eliminates forming edge defects that may lead to sheet breaks
• Paper edge trim system not affected by sheet speed, moisture, caliper, or tension

ROI

• Able to sustain narrow trim down to 15mm (0.6″) for maximum product on the reel
• Production costs are significantly improved as only rolls with hole defects or requiring splicing must be re-reeled
• Increased machine speed
• Sheet edges are directed to the machine pulper, bypassing any broke chest
