An elastic composite structure includes a first web layer comprising a first portion, a second portion, and a third portion; a second web layer comprising a first portion and a second portion; and a plurality of elastic threads. The first portion of the first web layer is folded over and overlaps the second portion of the first web layer. The folded first portion of the first web layer is directly bonded to one of the second portion of the first web layer and the first portion of the second web layer. A first portion of the plurality of elastic threads is constrained between the folded first portion of the first web layer and the second portion of the first web layer absent adhesive. The third portion is directly bonded to the second portion of the second web layer and traps a second portion of the plurality of elastic threads therebetween.

Elastic entrapment with waist cap bonding

A machine and method for manufacturing an elastic composite structure for disposable sanitary products involves manufacturing the elastic composite structure with an elasticized leg and leg cuff region in a manner that minimizes or eliminates the use of consumable adhesives. The elastic composite structure includes pairs of leg bonds and cuff bonds that are formed without adhesive and anchor respective leg and cuff elastic threads in position relative to facing web layers. The leg bonds and cuff bonds are formed using one or more anvils that include discrete raised projections.

Elastic composite structure for an absorbent sanitary product and an apparatus and method for making said elastic composite structure

Medical gown

An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes a bonding unit configured to bond a first web layer to a second web layer via a bond pattern that includes at least one bond line having at least one pair of adjacent bonds. The bonding unit secures an elastic thread within a passage defined by the at least one pair of adjacent bonds. The passage has a cross-sectional area smaller than a cross-sectional area of the elastic thread in a non-tensioned state.

Apparatus and method of manufacturing an elastic composite structure for an absorbent sanitary product

An apparatus for manufacturing an elastic composite structure for an absorbent sanitary product includes an anvil with weld pattern comprising at least one anchoring region and at least one deactivating region. The anchoring region includes anchoring welds that form anchoring bonds that fuse facing web layers and anchor elastic thread(s) in position relative to the facing web layers. The deactivating region includes a break bar constructed to sever the thread(s). A method of manufacturing the elastic composite structure includes positioning a tensioned elastic thread between web layers, fusing the web layers to form an anchored zone that includes anchoring bonds that fuse the web layers and anchor the tensioned elastic thread therebetween, and cutting the thread to form a deactivated zone between adjacent portions of the anchored zone that is free of tensioned threads. The method further includes fusing the web layers within the deactivated zone.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.

Method and apparatus for improved ultrasonic bonding

An apparatus for manufacturing an elastic composite structure is provided. The apparatus includes an anvil having a face with a first edge and a second edge separated in a cross-machine direction and a first contact surface extending out from the face, the first contact surface including a first notch. The first notch has an interior configured to receive a portion of an elastic thread and a portion of a web layer therein, and the first notch includes a first facing surface and a second facing surface defining at least a portion of the interior. Each of the first facing surface and the second facing surface are in a non-perpendicular orientation relative to the first contact surface and angled toward the first edge of the face.

Curved elastic with entrapment

An apparatus for splicing comprises a first web support surface configured to support a traveling web thereon and a second web support surface configured to support a replacement web thereon. The first traveling web travels in a machine direction. The splicing assembly also comprises a first web sensor and a web joiner. A controller is configured to determine, via the first web sensor, a position of a trailing end of the traveling web and to, in response to determining the position of the trailing end, cause a leading end of the replacement web to be positioned adjacently to the trailing end. The computer is also configured to control the web joiner to create a joint coupling the trailing end to the leading end.

Apparatus and method for splicing a web of material

An apparatus for applying elastics to a running web including a crank and arm, the arm arranged to reciprocate from side to side during use and having a laydown carriage carried on the arm, the laydown carriage including at least one eyelet arranged to support an elastic strand, the assembly further including a shoe guide.

Apparatus and method for applying parallel flared elastics to disposable products and disposable products containing parallel flared elastics

The present invention provides a method of providing a disposable product with zero waste ear formation and attaching the ears to a running chassis web.

Method for application of nested zero waste ear to traveling web

A web splicing apparatus is disclosed that includes a web unwinding unit configured to hold a running web material roll and a new web material roll and to unwind webbing from the running web material roll and a web splicing unit operable with the web unwinding unit to selectively splice the webbing of the running web material roll with webbing of the new web material roll. The web splicing unit further includes a cutting assembly configured to selectively sever the webbing of the running web material roll, a web deflection device, an actuator system configured to linearly translate the web deflection device in a first direction and a second direction opposite the first direction, and a locking mechanism operable in a locked state and an unlocked state to selectively prohibit and enable movement of the web deflection device in the first direction and the second direction.

Apparatus and method for splicing material rolls

An apparatus for manufacturing an elastic composite structure includes a first roller configured to transport a web layer in a machine direction and a laydown guide configured to guide a laydown pattern of a plurality of elastic threads. A rotary anvil comprises a first weld line having a first notch formed in a contact surface of the first weld line, the first notch having a first interior configured to receive a portion of a first elastic thread of the plurality of elastic threads and a portion of the web layer therein. The first notch comprises a facing surface defining at least a portion of the first interior. A smallest orientation angle of a first face axis normal to the facing surface with respect to a contact surface axis normal to the contact surface is a first angle that is less than 90 degrees.
