FAQ

Abrasive Cutting Knives are industrial cutting tools specifically designed for cutting abrasive rolls such as sandpaper and abrasive cloth.

Dished knives are circular cutting tools used for shear-type slitting. Unlike completely flat “flat knives,” their blades feature a concave geometric shape (resembling a plate or dish), a design that enables them to generate specific lateral cutting forces during rotational shearing.

Adhesive materials: Self-adhesive labels, adhesive tape, various composite films (die-cutting can create a temporary seal along the cut edges).
Elastic/soft materials: Rubber, non-woven fabric (NWF), textiles, tissue paper.
Abrasive/hard materials: Materials such as sandpaper that can quickly wear down standard sharp blades.

Yes. Flat Knives can be regrinded multiple times. Because Flat Knives are machined, they feature high precision and sufficient material allowance, making them ideal for multiple regrinds to restore their original sharpness.
Recommendation:
Have the regrinding performed by the original manufacturer or a professional regrinding service provider to ensure that the concentricity, end face runout, and cutting edge angles meet the original specifications after regrinding.
Proper regrinding can significantly reduce the cost per cut.

Multi-slot bottom knives, often referred to as multi-slot, multi-blade, or multi-groove bottom knives, are a specialized design that integrates multiple cutting edges onto a single blade body.
Here’s how you can visualize their structure:
Traditional bottom knife: A single blade body with only one cutting edge, requiring a spacer sleeve to determine the slitting width.
Multi-slot bottom knife: A single blade body with multiple cutting slots/edges arranged at equal intervals, with each slot corresponding to a slitting station.

Equipment: Slitting and rewinding machines, paper cutters, label/tape processing equipment, nonwoven fabric production lines Materials: Paper, film, aluminum foil, nonwoven fabric, tape, label materials
