Apparatus and method for vacuumizing and sealing a package
An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.
Methods and apparatuses for making elastomeric laminates with elastic strands unwound from beams
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.
METHOD AND APPARATUS FOR ASSEMBLING ABSORBENT ARTICLES
The present disclosure relates to methods and apparatuses for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure include providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; providing an elastic material; elongating the activated elastic material using a spreader mechanism; and ultrasonically bonding the first substrate together with the second substrate with the elongated activated elastic material positioned between the first substrate and the second substrate using an anvil and an ultrasonic device.

Production method and production device for three-dimensional decorative piece made of thermoplastic synthetic resin
A method and a device with which a bulky decorative piece made of a thermoplastic synthetic resin can be produced. A method for producing a three-dimensional decorative piece made of a thermoplastic synthetic resin includes a step of preparing a decorative piece material including an upper layer that has a thermoplastic synthetic resin film and a lower layer that has a thermoplastic synthetic resin sheet, a step of disposing the decorative piece material on a flat-plate die serving as an electrode, and a softening step of softening and welding the decorative piece material by bringing a flat-plate die serving as another electrode closer to the flat-plate die serving as the electrode, and performing high-frequency dielectric heating while pressing the decorative piece material.
Tube joining device
A tube joining device includes a delivery with a first pusher member providing forward movement and backward movement along a delivery direction and delivering a wafer to a first position between a take-out position and a stand-by position, and with a second pusher member providing forward movement and backward movement along the delivery direction in combination with the first pusher member, and the wafer from the first position to the stand-by position.
Heating element for inflation and sealing system
A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism. The sealing mechanism includes a heating zone and a cooling zone. The sealing mechanism also includes a heating element that extends along both the heating zone and the cooling zone, with the heating element having a first profile in the heating zone and a second profile in the cooling zone.
Assembly for forming bags
An assembly for forming bags, having a belt drive for feeding a film at a film speed to a former shoulder to form a tubular film, a set of jaws movable at a jaw speed to engage and seal a tubular film to form a closed bag, and a sensor assembly to provide a volume signal indicative of a volume of the closed bag, wherein the controller is configured to adjust at least one of the film speed and the jaw speed in response to the volume signal.
METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES

System and method for applying a fastening material to a substrate
A system for applying a fastening material to a substrate is provided. The system may include a first material source including the substrate. The substrate may define a first length extending from a first edge to a second edge and the first material source may feed the substrate in a first direction transverse to the first length. The system may additionally include a second material source including the fastening material. The fastening material may define a second length extending from a third edge to a fourth edge, whereby the second length is substantially equal to the first length and the second material source feeds the fastening material in a second direction transverse to the second length. The system may also include an applicator system that secures the fastening material to the substrate.
