Spring sofas and mattresses are one of the primary pieces of furniture in our homes that provide us comfort in our daily life. However, the bonnell springs start to sag that creates an uneven surface characterized by ‘peaks and valleys’ in areas across the sofa or mattress, in turn making for an uncomfortable sofa to sit and mattress to sleep on

LM-SM-1200 is a machine that easiest the production process since the upper inclined part applies pressure to the carcass to enable the spring sag beforehand that may occur later on

Working principle of spring fatigue machine:

• The lower and upper belts located in the machine are movable and the operator inserts the carcass into the machine between them
• While the carcass is moving with the help of movable belts, the carcass is compressed by the upper inclined belt
• With the help of the movable belts, carcass comes out of the machine automatically

Spring fatigue machine enables the spring sag app 5-10 mm in the carcass and prevents spring tension as well as product deformation beforehand that may occur later over time

One operator is being required
