A composite laminate reinforcing tool may be used to form a reinforced joint at a bond line of a composite laminate structure. The tool may hold one or more clips having posts, and the tool may be positioned along the bond line between at least two composite laminate elements. Joint sections of the clip may be heated to increase a pliability of the joint section, and the tool may be actuated to drive the post through the at least two composite laminate elements. The posts may be deflected toward a base of the clip, thereby to seat the clip. The reinforced composite laminate structure may then be cured.

A control circuitry (11) comprises an adjustable capacitor (C1), and a bias source (111) configured to apply a bias voltage (V2) to said adjustable capacitor (C1) to adjust a capacitance value of the adjustable capacitor (C1). Such a control circuitry may for example be part of a sealing device (1) to seal a medical tubing (2), the sealing device (1) comprising a receptacle (100) to receive said medical tubing (2), the receptacle (100) comprising an electrode arrangement for causing a heat action on the tubing (2).

There is provided a sealing apparatus for a cryopreservation bag, with which a sealing treatment of an inlet/outlet of the cryopreservation bag is carried out automatically and anyone can safely and properly carry out the sealing treatment. The sealing apparatus includes: a bag clamping device 56; a laser device 57; and a scanning structure 58 for moving the bag clamping device 56, for example. The bag clamping device 56 includes a fixed pinching block 67, a movable pinching block 69, and a clamp actuator 70. The laser device 57 includes a laser oscillator 104 and a condensing lens 107. The fixed pinching block 67 includes a block base 73, a heat radiator 74, and a heat radiator holder 75. An infrared laser beam is radiated to a sealed portion 55 of the bag to form a seal bead 125 for sealing in a state in which the sealed portion 55 is pinched and fixed by the heat radiator 74 and the movable pinching block 69 and while the bag clamping device 56, for example, is moved by the scanning structure 58.

An apparatus to apply a foam seal to a part is provided. The apparatus comprises a receiving device to secure the part, a loading device and a driving device to drive the loading device. The receiving device includes a housing, a first rod coupled to the housing and at least partially disposed in the housing and a resilient member connected between the housing and the first rod at a radial direction. The loading device includes an actuating member and a holding member to hold the foam seal. The driving device is configured to move the loading device between a loading position and an application position and further drive the actuating member and the holding member to rotate around an axis parallel to the first rod. The actuation member contacts the housing while rotating and the foam seal on the holding member contacts the part at the application position.

A heat sealing machine and method form blister packages. A backing material web extends between a nesting tray assembly and a seal and cut tooling assembly and a blister tray is resident within a blister nest of the nesting tray assembly. The backing material web is clamped between a clamping gasket support shoulder of the nesting tray assembly and a clamping shoulder of the seal and cut tooling assembly, and between a sealing gasket support shoulder of the nesting tray assembly and a heat seal shoulder of a heater assembly. A knife of the seal and cut tooling assembly extends between the clamping gasket support shoulder and the sealing gasket support shoulder to cut a backing sheet from the backing material web that is heat sealed to an attachment surface of the blister tray to form the blister package.

A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.

A jaw support and a sealing jaw for form, fill and seal machines are provided. In alternative embodiments, the form, fill and seal machines may include a fitment applicator station, a fitment applicator, a fitment heater assembly and a sealing jaw constructed and arranged to form a container and transfer and apply a fitment to the container.

An apparatus for producing an improved friction-fused welded joint is provided for use with overlapping thermoplastic strap portions. In an embodiment, the gripper is caused to swing back and force with a sufficiently large stroke and with a sufficiently fast stroke to cause sufficient reciprocation to rapidly heat the thermoplastic so that the two straps are welded together while reducing the depth of the area that is melted compared to traditional methods. Also, in an embodiment, a method is provided for stopping the relative motion of the two portions of straps with the portions of the plastic straps oriented in the same aligned relative positions at the end of the welding operation as at the beginning is disclosed.

A work station for a packaging machine comprises a tool structure and a tool movable relative to the tool structure by means of a drive. The drive comprises at least one countermagnet which is operatively connectable to an electromagnet and movable relative to the electromagnet. The drive further comprises a mechanism by means of which the movement of the tool is unidirectionally coupled to the relative movement of the countermagnet relative to the electromagnet.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.
