APPARATUS FOR FABRICATING AN ELASTIC NONWOVEN MATERIAL
An apparatus for fabricating an elastic nonwoven material generally includes a first bonding module and a second bonding module. The second bonding module is positionable in close proximity to the first bonding module for receiving a first nonwoven fabric, a second nonwoven fabric, and at least one elastic strand therebetween. The second bonding module has a face with a width dimension and a circumferential axis and is rotatable about a rotation axis. The face has a plurality of ridges includes a first ridge and a pair of second ridges positioned on opposing sides of the first ridge along the circumferential axis. The first ridge defines a plurality of interspaced lands and notches, and the second ridges are configured to sever the at least one elastic strand when in close proximity to the first bonding module.
Localized panel stiffener
A device (10) comprising a carrier material (14) and a matrix material (12) deposited onto the carrier material in a pattern that leaves a predetermined amount of space (18) between each deposition of matrix material.
Bonding objects together
A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.
Tabbed Seal Concepts
Tabbed sealing members with a robust tab structure having additional support under the tab and at a tab pivot or hinge joint.
Process for sealing flexible fitment to flexible film
The present disclosure provides a process. In an embodiment, the process includes A. providing a fitment with a base, the base comprising an ethylene/-olefin multi-block copolymer; B. placing the base between two opposing multilayer films, each multilayer film having a respective seal layer comprising an olefin-based polymer; C. flat sealing the base to each multilayer film with opposing heated flat seal bars, the flat sealing forming opposing seal joints at the flattened base ends; and D. point sealing the opposing seal joints with opposing curved seal bars.
METHODS AND FORMULATIONS FOR BONDING DISSIMILAR MATERIALS
The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.
METHODS FOR ULTRASONIC FABRICATION AND SEALING OF MICROFLUIDICS
Method of manufacturing a microfluidic device comprising an inflexible polymeric substrate, one or more flexible polymeric substrate(s) and one or more microfluidic channel(s) enclosed between the substrates comprising a) providing a master form including rim protrusions defining an enveloping shape for the microfluidic channel(s) to be produced and enclosed between the substrates, b) placing one or more flexible polymeric substrate(s) each having a layer thickness of less than 800 m onto the master form, wherein one flexible polymeric substrate is in contact with the rim protrusions of the master form, c) placing an inflexible polymeric substrate with a layer thickness of equal to or more than 800 m onto the flexible polymeric substrate(s), and d) ultrasonically welding the one or more flexible polymeric substrate(s) and the inflexible polymeric substrate at the rim protrusions. By the inventive method microfluidic devices via ultrasonic welding without using energy directors can be obtained.
TISSUE SUBSTITUTE MULTILAYER MATRIX AND USES THEREOF
Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.
Tabbed seal concepts
Tabbed sealing members with a robust tab structure having additional support under the tab and at a tab pivot or hinge joint.
