Welding method
A method for welding a first hose end at a joint with a second hose end in a seam that extends on a circumference of the first hose end, the method comprising the steps: applying a protective layer at the joint to an inside of the first hose end; pushing the second hose end beyond the joint over the first hose end; pressing the first hose end and the second hose end together flat at the joint between two first damping jaws that are moved towards each other; welding the first hose end and the second hose end together by two first partial seams while pressed together, wherein the protective layer prevents a welding of the inside of the first hose end; releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams.

Ultrasonic bonding of security device to a substrate to prevent harvesting
A security document (200) includes a substrate (205) having a first surface and a second surface opposite to the first surface, the first surface having a cellulosic material. The security document further includes an optical security device (220) having optical indicia of authenticity of the security document and a third surface, the third surface having a thermoplastic polymer. The security document also includes an ultrasonic weld (225) forming a bond between a section of the first surface and a section of the third surface.
COMPOSTABLE AND BIODEGRADABLE WET WIPE PAD FOR CLEANING MOP HEADS
A wet wipe pad designed to be connected or attached to floor mop heads or other cleaning tool handle that utilize a hook-and-loop mechanism for attaching the wipe pad thereto. The wipe pad can be made of multi layers of material that may include a cleaning layer ultrasonically welded to an attachment layer having an absorption layer disposed between the cleaning layer and the attachment layer. Alternatively, the wipe pad can be made from a single layer of material that can attach on one side thereof to the mop head or other cleaning tool handle, which also provides a cleaning surface on the other side of the single layer of material. The wipe pad of the invention may also be constructed from two layers of material that include a cleaning layer ultrasonically welded to an attachment layer. Regardless of the number of layers used in the wipe pad of the invention, the wipe pad is configured with at least one linking ribbon or tape strip of non-looped straight-line fibers extending along the length of the attachment layer and which forms the means or mechanism for releasably securing to hooks disposed on the mop head. The wipe pad, including its layer(s) and the linking ribbon or tape strip is constructed of materials that are compostable and biodegradable, making it an environmentally friendly product.
Marked thermoplastic compositions, methods of making and articles comprising the same, and uses thereof
An article for laser marking can comprising: a thermoplastic composition comprising a thermoplastic polymer, an active component comprising at least one of a polymeric unit and an additive, wherein the thermoplastic polymer has a visible transmission of greater than or equal to 80% according to ASTM D1003-00, Procedure A, using D65 illumination, 10 degrees observer, and thickness of 1 mm; and a mark produced by chemical rearrangement of the active component generated by a laser of a first wavelength; wherein the mark exhibits at least one of: (i) a change in optical properties in the region 400 nm to 700 nm when exposed to light having a wavelength less than or equal to 500 nm; and (ii) a change in optical properties in the region of 400 nm to 700 nm when exposed to light having a wavelength greater than or equal to the first wavelength.
