A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

A method for operating a tubular bag machine with a drive control system and multiple electronic drive units controlled independently of each other for driving functional elements of the packing machine in a cycle time-synchronous manner through predefined motion sequences, one drive unit being a transverse sealing unit with a drive motor driving two transverse sealing jaws for transversely sealing a film tube, and at least conversion functions for converting the drive torque and the position of the drive motor into the sealing force between the transverse sealing jaws being stored or calculated in the drive control system, the method including determining the operating temperature of the transverse sealing jaws, selecting or calculating a conversion function as a function of the operating temperature, using the temperature-dependent conversion function in calculating the drive torque of the drive motor required to reach a desired target sealing force between the transverse sealing jaws.

A vertical form fill and seal apparatus, for packaging particulates, includes a package sealing assembly that has opposed sealing jaws operatively coupled to each other by mechanical connection at a common pivot point. A first jaw actuator is mechanically coupled to the opposed sealing jaws to pivot the jaws in a controlled manner about the common pivot point. A second actuator is mechanically coupled to the package sealing assembly and is configured to impart controlled reciprocating motion to the package sealing assembly. A controller is configured to control the first actuator and to control the second actuator thereby causing the jaws to describe a preset locus of travel, allowing flexibility of type of bag being made without change-out of jaws. The packaging film may move continuously, or may optionally be controlled to move intermittently through the VFFS.

A method of rivet bonding a workpiece stack-up that includes one or more polymer composite workpieces, such as carbon fiber composite workpieces, involves several steps. In one step, adhesive is applied to a surface of the workpiece stack-up. In another step, workpiecesincluding the polymer composite workpiece(s)are brought together. In yet another step the adhesive is partially or more cured. A rivet is installed through the workpiece stack-up and through the adhesive in another step. The method strengthens the resulting rivet-bonded joint by minimizing or altogether precluding fracture, cracking, and/or delamination thereat.

A device of adjusting registration of plastic flooring contains a rolling unit and an adjusting unit. The rolling unit includes a press roller set having a first press roller, a second press roller, a third press roller, and a fourth press roller. The rolling unit delivers a substrate, a printing layer, and an anti-abrasion layer to the press roller set so as to be pressed together by the third and fourth press rollers. The printing layer has a pattern area, and the third press roller has a pressing pattern section. A first end of each of the third and fourth press rollers is connected on a fixed segment, a second end of each of the third and fourth press rollers is connected on a movable segment, and the adjusting unit is fixed outside the movable segment. The adjusting unit includes at least one power source and a movable rod.

Various device embodiments perform a sealing operation on a moving web, and comprise, among other things a plate assembly with an air cylinder assembly. The air cylinder assembly comprises a mount, a back plate, at least one air cylinder positioned between the mount and the back plate. The first plate assembly further includes a linear servo motor for linearly moving the air cylinder assembly with respect to the first base, and a first tooling plate with a sealing surface area. The first tooling plate coupled to the back plate.

An ultrasonic welding method for joining a first thermoplastic part and a second thermoplastic part without causing visible read-through on an exposed surface of the second part. The method includes arranging the first part on an inner surface of the second part. The inner surface is opposite the exposed surface. The first part has an interface portion contacting the inner surface. The method includes causing a horn of an ultrasonic welding stack to be pressed against the first part by applying ultrasonic energy oscillating at a frequency in a range of 45-70 kHz through the horn, to thereby join the first part and the second part together. The horn has at least one protruding distal portion configured to penetrate through the first part as the ultrasonic energy is imparted through the horn. The distal portion has a length longer than a thickness of the first part. A collapse distance of a weld formed at the interface portion is less than the thickness of the first part, to avoid read-through effects on the exposed surface of the second part.

A plastic welding machine for welding plastic parts together is capable of controlling the weld force vector in both magnitude and direction.

A method for monitoring a tubular bag machine having a drive control system and independently controlled electronic drive units controlled by a drive control system for driving functional elements of the packing machine in a cycle time-synchronous manner in predefined motion sequences, one drive unit being a transverse sealing unit with a drive motor and two transverse sealing jaws for transversely sealing a film tube, and the drive motor torque measured using a drive controller, and the drive motor position measured using a position sensor, the method including moving the film tube into the sealing zone between the transverse sealing jaws, closing the jaws according to a predefined target torque stored in the drive control system, measuring the actual position of the drive motor upon reaching the target torque, and comparing the measured position to a target position stored in the drive control system associated with the predefined target torque.
