Light Duty Belts
Light Duty conveyor belts are used on every machine in LAUNDRY FINISHING departments: feeders, ironers, folders, and small piece folders.
The largest belt type by volume is Cotton. Economy is important, but, the main reason for the extensive use of cotton is static control. Laundries are generally humid, but the finishing department takes damp linens, frequently with a high synthetic component, and pulls these damp linens across a very hot dry metal heating vessel to dry and impart a finish. Static is inevitable due to the synthetic fibers, hot and dry equipment, friction of travel.
Cotton belts absorb some of this static, and do not generate any.
This cotton belting can come in specialized constructions: elastic, or rubberized surface for traction.
Anti-Static belting is available to deal with the static problems described above. Our Anti-Static belting is specially manufactured of cotton and synthetic fibers and grounding threads. These will outlast 100 % cotton by a factor of two or three. So, in addition to handling static, this material provides long life and reduced maintenance.
One very special category of belts is perforated. They travel over vacuum beds and the holes or perforations allow suction to hold damp linens in place during travel through feeders, and into ironers.
The load carried by most laundry belts is very light. Therefore, there are no great tensile stresses. Stretching of light duty belts occurs, mostly due to age, and deterioration of natural fibers.
Conventional modern folders might also use rubber belting, chosen for surface characteristics:
rough for friction to move loads up conveyors
textured/semi-rough where gaps limit thickness, pinch-points increase consequences of friction
smooth where little friction is required, wanted, or even where slippage might be preferred
The most modern and flexible function folders have mostly rubber belts; these are much thinner and very flexible, stronger yet lighter, the same surface characteristics: smooth, semi-rough, and rough are available.
Belt specifications include width and length. Cotton and finished materials are made in the widths required. Rubber and non-woven materials can be slit to infinite widths.
Length measurement accuracy requirements vary with ‘take-up’ or pulley adjustment
Length measurement accuracy requirements increase with the quantity of belts using a pair of pulleys
Some machines do not allow for pulley adjustments
Modern belt specialists have automatic material measuring and cutting equipment, operating to +/- 1mm lengths over 50 pieces.
