An example system comprises a water-soluble unit dose article comprising a fibrous non-woven sheet shaped to form a sealed internal compartment and a granular laundry detergent comprised within the internal compartment. The sheet comprises fibres which comprise polyvinyl alcohol polymer. The granular laundry detergent comprises perfume particles. The system also comprises sealing jaws, whereby at least one of the sealing jaws is a heated sealing jaw. A top seal of the internal compartment is sandwiched between the jaws. A first of said jaws comprises a protruding portion along a longitudinal direction of the seal. The protruding portion has a base along a direction perpendicular to the longitudinal direction of the seal. The base has a dimension of more than 3 times and of less than 20 times a thickness of the water-soluble fibrous non-woven sheet.

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 that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.

To acquire a stretchable sheet having air permeability due to the presence of through-holes, with no hole formed through outer layers. There are provided: interposing a resilient film (30) that stretches and contracts, in a stretched state between a first sheet layer (21) having no elasticity and a second sheet layer (22) having no elasticity; and joining the first sheet layer (21) and the second sheet layer (22) together with a number of joints directly or through the resilient film by melting the resilient film (30) with ultrasonic fusion energy applied by a thermal fusion device from the outside of the first sheet layer (21) and the outside of the second sheet layer (22) to a number of joint regions with intervals, during the interposing. The resilient film (30) is supplied around a counter roll (63) so as to be supplied around the anvil roll (60), and the anvil roll (60) is accelerated to be faster than the counter roll (63) in peripheral speed to stretch the resilient film (30).

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

An adjustable sealing apparatus and corresponding method of use is disclosed. The sealing apparatus has a variable range of motion programmed to accommodate multiple types of sealing motion, including the reciprocal motion and rotary motion. The proposed design uses two sealing jaw units with each sealing jaw unit located on opposing sides of a continuous layered film. Each sealing jaw unit has a sealing jaw coupled to a distal end of extendable linkages. The sealing jaws are extendable to allow the sealing surfaces to engage one another at a plurality of sealing locations along a plurality of sealing paths. Moreover a control unit is communicatively coupled to each of the sealing jaw units and controls movement of the sealing jaw units to engage one another at one or more of the plurality of sealing locations which enables sealing of the film to produce bags.

The invention relates to a device comprising a first fixing element, comprising a first fixing surface, a further fixing element, comprising a further fixing surface, and a folded planar composite, at least partially fixed between the first fixing surface and the further fixing surface; wherein the folded planar composite comprises a first composite region and a further composite region; wherein the first composite region comprises a first layer sequence, comprising, from the further fixing surface to the first fixing surface, a first composite layer, a second composite layer, a third composite layer and a fourth composite layer; wherein the further composite region comprises a further layer sequence, comprising, from the further fixing surface to the first fixing surface, the first composite layer, the second composite layer and the fourth composite layer; wherein the first composite layer comprises a first carrier layer, the second composite layer a second carrier layer, the third composite layer a third carrier layer, and the fourth composite layer a fourth carrier layer; wherein, in the first composite region, the first or the fourth carrier layer or each of both is characterised by a greater layer thickness than the second or the third carrier layer or each of both and in the further composite region the second carrier layer is characterised by a greater layer thickness than in the first composite region; wherein the further fixing surface comprises a recess and the first composite region and the further composite region are each at least partially located between the recess and the first fixing surface.

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.
