The lid portion has a first body, a first rib protruding from the first surface of the first body and extending along the first surface, and the storage section has a second body, a second rib protruding from the second surface of the second body and extending along the second surface. The first and second ribs have main welded portions welded at intersections crossing each other, and the lid portion and/or the storage portion has main welded portions extending from one of the first and second ribs to the other between the main welded portions adjacent to each other. The lid portion and/or the storage section has an auxiliary rib extending from one of the first and second ribs to the other between the adjacent main welded portions, and the auxiliary rib has a sub-welded portion that is welded to the other at the intersection with the other.

A bonder and a method for bonding corrugated sidewalls to a thermoplastic belt at a splice joint. Two heating jaw assemblies with complementary and confronting corrugated vertical faces clamp a thermoplastic belt to a base of the bonder with a corrugated sidewall section separated from the belt across a splice joint received in a corrugated slot formed between the confronting vertical faces. Corrugated bonding strips at the bottoms of the corrugated vertical faces apply heat to melt the bottom of the sidewall section on opposite sides to bond the corrugated sidewall section to the base.

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.

The present invention relates to a nozzle for cleaning a substrate capable of spraying deionized water for cleaning a substrate to the substrate, the nozzle including a first body made of a resin material and provided with a first part of a deionized water passage and a deionized water supply hole to supply the deionized water, a second body made of a resin material and provided with a second part of the deionized water passage and a plurality of spray holes to spray the deionized water to the substrate, a fusible protrusion provided in the first body or the second body along the deionized water passage and configured such that a part thereof is fused during ultrasonic welding, so as to couple the first body and the second body together, and a fusible protrusion accommodating part formed in the first body or the second body to accommodate the fusible protrusion.

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.

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.

A method and apparatus for making bags or pouches is disclosed. An ultrasonic sealer may be used to form the seals. Sealing patterns may be used to provide a desired strength profile.

A synthetic turf seam integration template system and method is provided that includes a template having a planar base including a longitudinal non-cutting edge and an opposing longitudinal cutting edge. The longitudinal cutting edge is not straight but has a predetermined curvature. In one aspect, a through-cut viewing slot extends longitudinally offset a predetermined distance from said non-cutting edge. Variations of the predetermined curvature patterns are disclosed. An optional connector allows connection of two templates to create a longer template for usage on longer seams. Also disclosed are methods of using the seam integration tool in creating an undetectable seam in synthetic turf.

A method for producing a breathable web, comprising: feeding a web on the surface of an anvil roller rotatable about its axis and having a plurality of welding protrusions cooperating with a welding element, welding said web at a plurality of welding spots on head surfaces of said welding protrusions and forming respective annular welding seams at said welding spots, about respective welding projections, and respective thin membranes located within said annular welding seams and adjacent to the head surfaces of said welding protrusions, and removing said thin membranes after said welding by means of a peeling roller having an outer surface tangent to said head surfaces of said welding protrusions.
