Long fibre decortication lines
From bale to fibre — a complete turnkey line
Long fibre decortication lines
Cretes designs complete lines for decortication of long fibre — from automatic bale opening to sorting of the finished textile raw material. Multi-stage decortication preserves fibre length and strength at every stage, and capacity and configuration are selected to suit the plant's project. Technology for flax and hemp processing plants, supported by engineering service and operator training.
Flax is a chain: from seed, through harvest and scutching, to industrial fibre.
Van de Bilt (genetics and seed) → UNION (harvest) → CRETES (scutching) → Vanhauwaert (fibre processing). Each machine serves one link of the same process.
One group closes the entire flax chain
Cretes does not operate in isolation — it belongs to Valtech Group, which covers the other links of the same process: harvest, scutching and pressing. Each link is a different machine, but one technological line.
- 01Harvesting
UNION
Pullers, inverters and baling presses work in the field — from pulling flax to straw harvesting (GX220, GX240, GX255).
See UNION machines - 02Scutching / beating
CRETES
Multi-stage beating, cleaning of by-products and sorting — long fibre of textile grade.
Ta strona - 03Pressing / baling
VALVAN
Baling and packing of the finished fibre at the end of the line. Partner of Valtech Group for baling presses.

Complete line for hemp processing
Cretes designs hemp fibre processing as a complete line — from bale opening, through scutching, to separation into fibre, shives and dust. The “complete line” approach means one coherent sequence rather than loosely assembled machines, expandable and adaptable to the needs of the plant.
- Handling of weakly and heavily retted raw material (retted / non-retted).
- Round and rectangular bales; optimal operation at moisture 11–18%.
- Line that can be expanded and “tailor-made” (upgradable / tailor-made).
- Cretes Tech Center — validation of raw material and the whole business case before investment.
- 25–28%
- premium cleaned fibre (<1% shives)
- 50%
- high-grade dust-free shives
- 15–17%
- dust
- 5–7%
- short fibre with shives
Proportions according to the Cretes catalogue (European hemp varieties) — depend on raw material and line configuration.



- 01Complete turnkey lines — from design through commissioning and operator training
- 02Multi-stage decortication — preserves fibre length and strength better than single-stage machines
- 03Technology for flax and hemp — one solution for two raw materials
- 04Part of the Valtech group — the complete flax chain in one group: harvesting (Union), baling (Valvan), decortication (Cretes)
- 05Over 100 years of machine-building tradition (since 1908, CRETES brand since 2013)
Wevelgem, West Flanders, Belgium
Cretes originates from Werkhuizen Constant Van Dommele, which has been building machines since 1908. The CRETES brand was created in 2013 from the merger of Van Dommele and Rolls — manufacturers of machines for the textile industry — hence over a hundred years of experience. The company, based in Wevelgem (West Flanders), belongs to the Valtech group, which closes the entire flax chain: UNION (harvesting), VALVAN (baling) and CRETES (decortication and processing), complemented by Callebaut de Blicquy (dyeing and bleaching). Cretes has moved from single machines to designing complete turnkey processing lines — for flax and industrial hemp — with installations including in Belgium, France, the Netherlands and Poland.
