(1) fiber ball
3-dimensional curling of chemical fiber ---- Pearl size chemical fiber ball forming machine ---- Filling machine for pillow ---- Weight checking with electronic scale ---- Sealing of the opening with sewing machine
Advantage: Simple in production technique, minimum in seal length and the quickest in filling speed. Smooth in pillow appearance and full in four corners. For cushions with special structures, their appearance are also smooth.
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
Advantage: Less operators are needed because of the production line formed with carding machine and filling machine.
Good in apparent smoothness of the pillow.
Disadvantage: The pillow has a long seal. It is not applicable for small cushion and cushion with a special shape.
Slow in production speed in production line due to the small production speed of the carding machine.
Error of fixed weight is about 50 grams. Check of weight is still necessary.
(3) Filling with fitting plates
Chemical fiber ---- Felt forming by chemical fiber carding machine ---- Manual felt- cutting into pillow size ---- Filling with fitting plates ---- Sealing of the opening with sewing machine
Advantage: Investment is reduced by making use of the existing chemical fiber carding machine.
The pillow thus filled is smooth in appearance with four full right angled corners.
Disadvantage: The seal is as long as the width of the pillow itself.
It is slow in production speed.
