Various embodiments of the present disclosure provide a press-type strapping machine configured to strap a load when both the height of the load falls within a target height range and the compressive force applied to the load falls within a target compressive force range.

A relaxation device of a cardboard strapping machine includes a connector being movably extended into a top holder. When the connector retreats from a connective channel in the top holder, a middle pressure lever descends to loosen the overlapping straps, so that the overlapping strap is not pulled by the retracted connector to cause misalignment, the adhesion area is complete, and its adhesion strength is good. In contrast, a cardboard pile cannot be fastened by the strap, which is deformed by a drag force when a counter-pressure plate is pulled back, through a traditional strapping machine for bundling cardboards. Furthermore, another forcibly pull-off implementation will weaken the connection strength at an overlapping portion of a strap head and a strap tail of the strap.

A strapping machine comprising: —a feeding device for feeding astrap (3) around one or more objects and subsequently retracting the strap to draw it tightly around said objects; —a welding device for forming a welded joint between a first section at the leading end of the strap and an overlapping second section at the trailing end of a piece (3a) of the strap fed around said objects to thereby secure this piece in a loop around the objects; —a support member (24) for supporting said overlapping strap sections during the formation of the joint, a recess (25) being provided in an upper support surface (26) on the support member; and—a pressing element (27) with a shape adapted to the shape of said recess, the pressing element and support member being configured to form a permanent bulge (30) on the first strap section by a press forming action between the pressing element and the support member.

The invention relates to a strapping device and a method for producing strapped packages, which combine at least two articles by means of at least one strap. The strapping device is paired with a device for providing two or more grouped articles. and the strapping device comprises a handling device (10) with two pivoting arms (11, 12) which can be adjusted relative to each other and each of which is equipped with clamping devices (14, 15) for fixing the belt ends (27) of a strapping belt (26) or a strapping blank (28) in a clamped manner. The pivoting arms (11, 12) can surround the grouped articles for the purpose of strapping same, thereby pivoting the first pivoting arm (11) and the second pivoting arm (12). The strapping device additionally comprises a fixing device for connecting the two belt ends (27) of the strapping belt (26) or the strapping blank (28).

An ultrasonic cable tie system is disclosed herein. The ultrasonic cable tie system includes a housing having a tying portion for receiving a bundle of wires to be tied into a cable. The tying portion has an aperture for dispensing a cable lacing filament from a filament spool and for receiving a free end of the cable lacing filament after being positioned around the bundle of wires. The ultrasonic cable tie system also includes a controller coupled to a tensioning member for tightening the cable lacing filament, an ultrasonic welder for fusing the cable lacing filament, and a filament cutting device for cutting the cable lacing filament. The ultrasonic cable tie system is activated by a system actuator causing the controller to secure the bundle of wires together into the cable with the cable lacing filament having a flat fused portion adjacent to a surface of the cable.

The present invention relates to polyester straps, methods of their manufacture, systems and uses thereof, particularly as may be used in binding applications of discrete articles into bundles. The polyester straps comprise voids extending into the interior of the strap from one or more of the surfaces there
