The invention relates to a strapping device for strapping packaged goods with a strapping band, said strapping device being provided with a connecting device (5) designed as an ultrasonic welding device (9) in order to form a closure. The ultrasonic welding device (9) is provided with a sonotrode device (13) to which ultrasound generated by an ultrasound converter (10) can be transmitted, and the sonotrode device (13) has a contact surface (21, 24) in a provided region which contacts the strapping band. The contact surface is designed to contact a surface of the strapping band, and the sonotrode device (13) is designed to produce ultrasonic vibrations by means of the contact surface. The aim of the invention is to allow a more compact design for such strapping devices. This is achieved in that the contact surface (21, 24) of the sonotrode (11) is aligned at an angle which deviates from a right angle relative to the provided vibration direction of the sonotrode (11).

Systems and methods are presented herein for a method of attaching a strip to a housing. An internal support member is inserted into a collapsible housing, such that it is arranged along a longitudinal axis of an inner surface of the collapsible housing. An outer support member is arranged along an outer surface the collapsible housing opposite the internal support member. A strip is positioned along the outer surface using the outer support member and the internal support member. Then the strip is permanently welded to the outer surface using a welding element. Welding is performed by a welding element located in one (or both) of the internal support member or the outer support member.

A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

Method for the production of a pacifier teat and pacifier teat with a suction section forming a cavity, to which suction section a shaft adjoins, wherein an elastic hollow body having suction section and the shaft is pre-formed in an injection or in a dipping process and opposite wall sections of the pre-formed hollow body are connected with each other in the region of the shaft.

Disclosed is an intelligent automatic conical net making machine. The net making machine comprises a net winding device (3) and a net binding device (4). The net winding device (3) comprises a filter screen winding shaft (3.1), a filter screen winding drum (3.3) and a net winding power device (3.2). The filter screen winding shaft (3.1) comprises a conical hollow shaft body, and a strip-shaped net binding hole is axially provided in the hollow shaft body. The filter screen winding drum (3.3) comprises two arc-shaped plates (3.5) hinged together, and the two arc-shaped plates (3.5) can be driven by the net winding power device (3.2) to be opened and closed along a hinged shaft to wrap the filter screen winding shaft (3.1) without shielding the net binding hole. The net binding device (4) comprises an automatic stapler (4.1) and a stapler base mould (4.5), and the stapler base mould (4.5) of the net binding device (4) can be inserted into the hollow shaft body of the filter screen winding shaft (3.1). The automatic stamper (4.1) can cooperate with the stapler bottom mould (4.5) through the net binding hole to complete a net binding operation. The equipment can stably and reliably finish the net supplying, feeding, winding and binding process, is smooth in equipment operation, and is suitable for popularization and industrial production in the industry.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

A method and system for manufacturing a conical shaped acoustic structure. A sheet of acoustical material is cut to form individual pieces using a cutter system. Each individual piece in the individual pieces has a flat pattern for the conical shaped acoustic structure. An individual piece is positioned around a mandrel with a conical shape using an actuator system. Two edges of the individual piece are positioned for joining. The two edges of the individual piece positioned around the mandrel are joined to form the conical shaped acoustic structure.

A container formed of a common one-piece thermoplastic substrate. The container has an overlapping seam having an overlap magnitude. At a location that is five times the overlap magnitude away from the overlapping seam, the container wall has a container wall Opacity less than about 50%. At a corresponding position along the overlapping sea, the overlapping seam has a seam Opacity that is less than 200% of the container wall Opacity.
