1 Scope

This document describes a continuous machining process using chain or belt feed, manual loading and unloading, with a maximum workpiece height of 100mm.

Safety requirements and measures for edge banding machines (hereinafter referred to as machine tools).

This document addresses the hazards listed in Appendix A (Hazards List) related to machine tools when operated, adjusted, and maintained according to the manufacturer's intended specifications.

All significant hazards, dangerous situations, and events related to the device, including reasonably foreseeable misuse. Furthermore, transportation, assembly, disassembly, and decommissioning are also considered.

And the dangers of the scrapping stage.

The machine tool is designed to process one side (single-end machine tool) or both sides (double-end machine tool) of the following plates in a single operation.

---Materials with physical properties similar to wood (see GB/T 44902-2024, 3.2), even lightweight aluminum alloy core panels;

---Gypsum board.

The edge banding strips used in machine tools can be made from the following materials.

---Paper;

---Melamine;

---plastic;

---Composite materials;

---aluminum;

---Lightweight alloy;

---veneer;
