Some common repairs that diaper making machines may require include:
Broken or worn out needles
Diaper making machines use needles to punch holes for elastic threads and tapes. Over time, the needles can bend, break or wear down which impacts stitch quality and can jam the machine. Needle replacement is often needed.
Issues with the stitching mechanism
Problems with the stitch cam, stitch finger, looper or other stitching components can cause the machine to skip stitches, uneven stitching or jamming. These parts may need adjustment, repair or replacement.
Broken or stretched elastic threads
The threads used for elastic waistbands and leg gathers can break or stretch out over time with frequent use. Rethreading or replacing the elastic threads may be required to get proper tension and gather.
Trouble with feeding elastic or tape
Issues with the air pressure, feed rolls, feed fingers or other components responsible for feeding the elastic and tapes can prevent proper feeding. Diagnosing and repairing or replacing these parts gets the feeding mechanism working again.
Electrical problems
Things like bad motors, power switches, controllers, sensors, etc. can lead to the diaper making machine not operating properly. Electrical repairs or replacement of components may be needed.
Leaks or damage from spills
While diaper making machines are designed to handle liquids, spills and leaks can still damage internal parts over time. Any detected leaks should be addressed through repairs, cleaning or replacement of contaminated parts.
General wear and tear
Moving parts like gears, pulleys, bearings, extrusion components, etc. will naturally show some wear over the lifetime of a machine with heavy use. At some point, excess play, noise or poor performance indicates it is time for repair or replacement of worn out components.
Structural damage
Impacts, dents or other physical damage to the frame, tables, stands or other structures of the machine can impact safety, stability, alignment or function. Structural repairs may be needed to brace, weld or otherwise fix any detected damage before the machine can be safely operated.
Those are some of the common types of repairs that diaper making machines and other commercial sewing/extrusion equipment may require to keep them functioning properly. Preventative maintenance is also important to minimize downtime from unplanned repairs.
