Apparatus and methods for fabricating tote bags
11298914 · 2022-04-12 · ·

In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.

ADHESIVE ARTICLES PERMITTING DAMAGE FREE REMOVAL

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Waterproof and Wear-Resistant Composite Floor and Production Method
20210309003 · 2021-10-07 ·

A production method for a waterproof and wear-resistant composite floor, comprising: first manufacturing a PVC composite layer preform (3); then performing a corona treatment and a punching treatment on a soft cushion layer (2); and finally, compounding, at one time, the PVC composite layer preform (3), the soft cushion layer (2) and a waterproof substrate layer (1) into one. Said process is simple and easy to implement, shortening the production cycle, reducing the manpower and material resources required by the production process and reducing the production cost; moreover, the waterproof and wear-resistant composite floor produced has a simple structure, and also has very good waterproof and wear-resistant performance; in addition, the waterproof and wear-resistant composite floor will not swell, and will also not split into layers or deform easily.

METHOD AND SYSTEM FOR PRODUCING AN ENGINEERED WOOD
20210276218 · 2021-09-09 ·

The present invention relates to a method for producing an engineered wood, comprising the steps of: (a) breaking down a veneer to increase its porosity; (b) impregnating the veneer from step (a) with an adhesive material; (c) drying the veneer from step (b) to a predetermined moisture content level; (d) arranging a plurality of the veneers from step (c) in a mould; and (e) pressing the plurality of the veneers in the mould. The engineered wood has an appearance of natural timber, and is able to withstand extreme weather conditions and have minimum warping, rotting and termite infestation.

WOUND-CONNECTION PADS FOR FLUID INSTILLATION AND NEGATIVE PRESSURE WOUND THERAPY, AND SYSTEMS AND METHODS

Connection pads for coupling fluid-instillation and negative pressure wound therapy (NPWT) apparatuses to wound dressing, and methods and wound dressings for breaching a drape after coupling a wound dressing to a fluid-instillation and/or NPWT apparatus.

Elastic laminates, method of manufacture thereof and articles comprising the same

Disclosed herein is a multilayer laminate comprising a film comprising an ethylene-based elastomer; a first non-woven layer in contact with a first surface of the film; and a second non-woven layer in contact with a second surface of the film; wherein the second surface of the film is opposedly disposed to the first surface of the film; wherein at least one of the first non-woven layer or the second non-woven layer comprises a non-woven web; and wherein the non-woven web is formed from a bicomponent fiber having a first component comprising an polyethylene-based polymer and a second component comprising a polymer having a melting point that is higher than the polyethylene-based polymer, wherein at least a portion of a surface of the bicomponent fiber comprises the first component.

Method for producing an integral join and automatic placement machine

A powder carrier, to which a powder layer containing a metal powder is applied, is provided by an automatic powder carrier feed. A first joining partner is pressed onto the powder layer located on the powder carrier so as to bond a powder layer portion to the first joining partner. The first joining partner is raised from the powder carrier together with the powder layer portion bonded to the first joining partner, and the powder layer portion bonded to the first joining partner is arranged between the first and second joining partners. A sintered join is produced between the first and second joining partners by pressing the first and second joining partners against one another such that the powder layer portion makes contact with both the first and second joining partners. The powder layer portion is sintered as the joining partners are being pressed against one another.
