A method of utilizing a scrim of elastic material including cutting the elastic strands within a disposable undergarment is disclosed. The method generally follows the steps of providing two webs of fabric and an elastic scrim of mesh-like design, adhering the scrim between the two webs of fabric, determining areas where elastic material is not required, compressing the non-elastic areas with a thermal compression tool, and forming a disposable undergarment.

A system for removing chips from a web is disclosed, the system having a rotationally variable speed shoe for receiving a chip, a rotationally constant speed transfer roll for receiving a portion of a web from a die and anvil system, with the shoe initially rotating at a constant speed, slowing to allow a portion of the web to rip away from the chip at a leading rotational edge of the chip, next increasing in rotational speed to allow the chip to rip away from the web at a trailing rotational edge of the chip.

A pants-type diaper, is provided which is equipped with leg-hole elastics which effectively encircle the leg-holes without traversing the crotch region. Also provided are methods for producing such diapers. Typical products of this type are provided with an outer laminate, formed of an inner liner material and an outer backsheet material between which the leg-hole elastics are disposed. The invention provides for the removal of a strip of inner liner material carrying undesirable crotch-region elastic strands prior to lamination or combining of the remaining inner liner with a complementary outer layer backsheet.

A web cutting system is provided for use with a single transfer insert placement mechanism having at least one puck for transferring a discrete web and a continuous web feeding mechanism for feeding a continuous web wherein first and second rollers having substantially parallel axes and being aligned with one another form a nip at their juncture, an anvil is attached to one roller, a die is attached to the other roller, a vacuum source is coupled to one of the rollers, a plurality of vacuum apertures is formed in the same roller. One of the rollers is positioned adjacent to the single transfer insert placement mechanism and to the continuous web feeding mechanism. The continuous web is applied to one roller and at least one discrete web is transferred from the puck to the same roller after which a die cutting process of the webs occurs at the nip.

An apparatus and method is provided for single transfer insert placement. The apparatus receives continuous web material and cuts a discrete section or pad from the web. The pad is then supported on a single transfer surface. The single transfer surface then may spin the supported pad to a desired angle and provide the pad to a receiving surface at a desired interval. The web material can be cut to different insert lengths and the placement location varied.

An elastic material is cut, set to a product pitch, stretched a desired amount and applied to a moving target web to create a product with a desired amount of elasticity over a desired area. A vacuum wheel with an aggressive vacuum pattern is used for securing and stretching the stretchable film, the same type of wheel also capable of being used as a trim removal device.

A pants type disposable undergarment is provided which is equipped with a pre-fastened pull-on pant with a side lap seam formed by the methods of the present invention, and methods for producing such disposable undergarments.
摘要:
A series of elastic break brakes are provided throughout a travel path of elastics in a machine operation. Elastic strands thread through each individual brake mechanism, and if an elastic strand breaks downstream, a natural snap back of the elastic, which ordinarily travels through the system under tension, drives an immediately upstream cam mechanism back, and holds the elastic thread in place at the elastic break brake immediately upstream of the break as to minimize rethreading required downstream of the elastic break brake.
