The present disclosure relates to methods and apparatuses for assembling diapers, each including a chassis connected with front and back elastic belts. As discussed in more detail below, opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. An elastic laminate may be formed by continuously bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer such that the elastic strands are bonded to both the first substrate layer and the second substrate layer in heavy-bond regions. And the elastic strands are bonded to the first substrate layer and/or the second substrate layer with in light-bond regions. The elastic strands are then intermittently deactivated by cutting the strands into one or more discrete pieces in the light-bond regions. The discrete pieces retract and remain in the light-bond regions.

Apparatuses and methods for making absorbent articles

A tape (12) includes a backing layer (22) and an adhesive layer (24) formed on the backing layer. A plurality of lines of perforations (32) extend across the tape to separate the tape (12) into sheets. The sheets have progressively increasing lengths such that, when the sheets are wound into a roll (10), each sheet is longer than the sheet underneath it. When in a roll, the outermost sheet covers all of the lines of perforations to reduce instances of the tape tearing in a downweb direction.

Progressively perforated tape roll

Adapters for solid or coreless rolls of material dispensed in a roll dispenser, which may have slots defined on the side walls thereof. The adapters may have a base body with a first side disposable adjacent to the roll and a second side disposable adjacent to the side walls of the dispenser. A protrusion may extend substantially transverse from the first side and may have a shape and length so as to extend at least partially into a recess or divot formed in the vertical sides of the rolls. An engaging member may extend substantially transverse from the second side of the body member and may have a shape and a length so as to be insertable into and slidable along slots disposed in the dispenser. A pair of the adapters may engage and hold the roll therebetween within the dispenser and may allow for the roll to move along the slots defined in the dispenser to a dispensing position.

Coreless roll product and adapter

A rewinder having a first winding roll that transports and supports the web, at least one core support plate that is curved for receiving and guiding cores adjacent the first winding roll, and a web separator adjacent the first winding roll and movable into pressing relationship with the web at a velocity at least equal to that of the web. The rewinder of exemplary embodiment winds a web of material a nip defined by the first winding roll, a second winding roll and a rider roll. The web separator of exemplary embodiments comprises a rotatable plurality of fingers that rotates about a common shaft. Because the web separator contacts the web moving at a velocity at least equal to that of the web, the web is effectively separated upstream of the web separator, between the core and the web separator.

Rewinder apparatus and method

A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.

Method for wetting and winding a substrate

A web cutter includes a knife roll located above an anvil roll, a web infeed conveyor for moving a continuous web to be severed to the nip between the rolls and a segment discharge conveyor for removing segments cut from the web. The roll includes a plurality of fixed cutting knives and the anvil roll includes a plurality of fixed anvils such that rotation of the rolls brings each knife into engagement with an anvil to sever the web. Lift plates on the anvil roll are located immediately upstream from each anvil to raise the severed lead end of the web above the anvil in order to assure proper feeding to the discharge conveyor.

Two roll web cutter and method

A machine and method for winding coreless rolls from an indefinite length web by winding a spiral body in a winding pocket with a trailing end extending upstream from the pocket, releasing the body from the pocket and accelerating the body and trailing end downstream away from the pocket while winding the trailing end onto the body to complete the roll and to create a gap between the trailing end and the leading end of a web fed toward the pocket. Fingers are extended through the gap to guide the leading end of the web and into the pocket and intricate winding of the next roll.

Roll winding machine

A machine to apply strips or webs of heat-sealable and/or heat shrinkable material around coiled rolls of sheet material to either band or wrap such rolls, or shrink such bands or wrapping web into close contiguous engagement with said rolls to prevent uncoiling of the same. The machine includes means to relax the tension on the strips or webs when the same are about to be heat sealed to encircle coiled rolls by means of anvil and heater bars which cooperate to engage said strips or web when encircling the rolls and heat-seal the same and simultaneously sever the encircling portions from the supply and also re-connect the severed portions by fusion to position the same across the path of the rolls through the machine for engagement by the rolls. Pusher means also push the coiled rolls into engagement with re-connected strips or web by means of guide mechanism for the pusher means which moves it horizontally. A removal conveyor also operates in association with a stationary member which supports the rolls while being encircled with said strips or web to remove the banded or wrapped rolls from the heat sealing means to carry them to additional heating means to heat-shrink the bands or wrapping webs around the coiled rolls.

Roll wrapping or banding machine

Temperature control means for a curtain-type wrapping or banding machine to prevent excess ambient temperature thereon by employing switch-actuating means responsive to even very small changes in the expansion and contraction of the elongated heating element on the heater bar of the machine which co-acts with the anvil thereof to effect sealing of either a web or bands of thermoplastic synthetic resin material around various types of objects of various sizes and also re-constitute the web or bands into continuous form incident to severing the sealed web or bands from the supply material.

Seal temperature control means for curtain-type wrapping machine

A machine and method for winding coreless rolls (202) from an indefinite length web (16) by winding a spiral body (202) in a winding pocket (92) with a trailing end (204) extending upstream from the pocket (92), releasing the body (202) from the pocket (92) and accelerating the body (202) and trailing end (204) downstream away from the pocket (92) while winding the trailing end (204) onto the body (202) to complete the roll (200) and to create a gap (224) between the trailing end (204) and the leading end (222) of a web (16) fed toward the pocket (92). Fingers (96) are extended through the gap (224) to guide the leading end (222) of the web (16) into the pocket (92) and initiate winding of the next roll (202).
