Solventless Lamination Machine for Flexible Packaging

Solventless lamination bonds two flexible films with a thin adhesive layer applied by a multi-roll coating head and pressed in a heated nip. We engineered the complete machine for a converting-machinery OEM: the main structure, the coating and lamination sides with nip drum and cooling roll, film guide and support roller assemblies, the adhesive trays and the electrical panel construction.

The challenge

Film path geometry, roller parallelism and nip pressure decide laminate quality, so the structure has to hold the roller bearings in line over the whole machine, and every roller — guide, support, nip, cooling — needs its own detailed assembly. The OEM wanted a complete Solid Edge dataset to replace a mix of older drawings.

Our approach

The main structure was modelled as a fabricated frame assembly with machined pads for the roller bearing housings, and each roller group was built as its own assembly: guide film assemblies with and without support rollers, the coating-side filter and tray assemblies, the lamination-side nip drum with the cooling roll, and the electrical panel construction.

Drawings were issued per assembly in the OEM's DFT template with the fabrication tolerance table, from the main structure assembly through the tray and roller assemblies, with photographs of the built machine used to verify the model during detailing.

What was delivered

The OEM received native Solid Edge assemblies, a 70-plus-sheet drawing set and STEP data for the complete machine, forming the documented baseline for their solventless laminator product.

  • Solid Edge machine assembly with roller and tray sub-assemblies
  • Fabrication drawings for the main structure
  • Machining drawings for rollers and bearing housings
  • Electrical panel construction drawings
  • STEP export

Standards and conventions applied

  • OEM drawing template and tolerance table
  • ISO 2768 general tolerances
  • ISO 2553 weld symbols
