摘要:
An apparatus to apply vibrations to partially or completely thermofusible articles, the apparatus including a vibrating working tool to cause a localized heating effect between it and a co-acting tool, partially or completely thermofusible articles positioned between the tool being, for example, cut or welded by the heat produced.

An apparatus for the ultrasonic welding and cutting of a pair of juxtaposed synthetic-resin sheets has a sonotrode and an anvil, one being engageable with the other, upon their relative movement toward one another. Mounted on the anvil or sonotrode is a spacer element is the form of a ridge running along the middle of the welding face of the tool. This ridge has a height slightly less than the combined thickness of the two sheets so that when the spacer ridge engages the opposite welding face it cuts the sheets while the surfaces of the face blanking the spacer ridge coact with the opposite face to form a welded seam.

A device for detecting defects during sealing of a package including a foil, and a method for detecting defects during sealing of a package including a foil which makes use of such a device. The device may include a distance sensor for determining the distance between at least two clamping elements, and a control unit coupled to the distance sensor for comparing the measured distances to predefined references. Such a device may be operated by, for example, positioning a foil and another part of a package to be connected to the foil between the clamping elements, moving the clamping elements toward one another until a connection between the foil and the other part of the package is formed, determining the distance between the clamping elements over a period, moving the clamping elements apart, and removing the package.
摘要:
The invention relates to a device for producing a web of corrugated cardboard comprising a first corrugating roller for producing a corrugated web. The device further has a glue application roller for applying glue to the corrugated web. The glue application roller is associated to the first corrugating roller so as to form a gap and is displaceable relative to the first corrugating roller in order to influence the glue application quantity. The device further comprises a displacement device for displacing the glue application roller relative to the first corrugating roller and a pressing device for pressing a laminating web against the corrugated web. It is further provided with a regulating device which is in signal connection with the displacement device, a gap regulating unit in order to adjust a gap width of the gap between the first corrugating roller and the glue application roller, and a contact force regulating unit in order to adjust a contact force applied to the first corrugating roller by the glue application roller.
摘要:
Systems and methods to improve weld quality are described. For example, certain systems and methods described use weld quality monitoring as feedback to an ultrasonic welding process to improve weld quality. Still other systems and methods provide improvement to double sided and single sided ultrasonic welding through the use of selected multiple pulses.

The invention relates to ultrasonic welding of industrial fabrics. Specifically, the invention relates to methods for ultrasonically welding the seam area of industrial fabrics using a textured horn and/or anvil. The fabric edges are overlapped as woven or one or both edges can have some warp or weft yarns raveled out. The method involves ultrasonically bonding the overlapped fabric edges, reducing the caliper of the two stacked edges to match the body caliper of the fabric itself. The bonded area can then be perforated using laser or other mechanical means to produce a seam having the same woven texture and permeability (air and/or water) as the body of the fabric.
