Can be also Fixed weight filling machine for pillow.
The products are high in technical element, endurable and high in sales price.
Disadvantage: Only 3-dimensionally curled chemical fiber can be adopted, 2-dimensionally curled chemical fiber can not be used. Raw material is expensive.
(2) carding and Fixed weight filling machine for pillow
Chemical fiber ---- chemical fiber carding machine ---- Filling fan ---- Weight check with electronic scale ---- Sealing of the opening by sewing machine
