The invention discloses an elastic
waistline shaping
machine for a
waist-surrounding paper diaper. The elastic
waistline shaping
machine comprises a
machine frame, a
rubber band output device, a non-woven cloth
output device, a
rubber band gluing mechanism, a non-woven cloth gluing mechanism, a half folding mechanism, a
cutting-off knife rest, a steering knife rest and a non-woven glue spraying mechanism, wherein the
rubber band output device is arranged on the front side face of the machine frame; the rubber band gluing mechanism implements gluing on the surface of each rubber band; the non-woven gluing mechanism implements gluing on the surface of the output non-woven cloth; the half folding mechanism folds the output non-woven cloth in half; the
cutting-off knife rest is installed on the front side face of the machine frame, and implements
breakpoint cutting-off on a part of the rubber bands; the steering knife rest is located on the right side of the cutting knife rest; the non-woven glue spraying mechanism is located between the cutting-off knife rest and the steering knife rest, and sprays glue onto the surface of the folded non-woven cloth. Compared with the prior art, the elastic
waistline shaping machine for the
waist-surrounding paper diaper provided by the invention has the advantages that, the shaped elastic waistline is of a
cut point structure corresponding to the rubber band of a part which coincides with an absorption core body, so that the part, corresponding to the absorption core body, of the elastic waistline has no elastic effect; therefore after the elastic waistline is combined with a paper diaper body, the wrinkling of the absorption core body is not caused.
