A sealing system (100) for sealing a packaging material is disclosed comprising an independently movable sealing device (101) being movably mounted on a track (102), a power generator (105) in communication with the sealing device (101) to supply a power signal (p1) at a frequency for said sealing over a power communication line (106), the sealing device (101) comprising a housing (107), a detection device (108) arranged in the housing (107) to register detection data of an environment therein and/or of sealing parameters associated with said sealing, and a transmitter (109) connected to the detection device (108), the transmitter comprising an encoder (110) to convert the detection data to at least one frequency pulse (p2), whereby the transmitter (109) communicates the at least one frequency pulse as a detection signal to a receiver (111) over the power communication line (106).

A wire embedding system and methods are presented. A wire is embedded in a substrate at predetermined locations in a series of sequential embedding instances using heat and pressure. The heat and pressure are removed from the wire in between the series of sequential embedding instances.

A method for testing a tubular bag machine, the tubular bag machine having multiple electronic drive units controlled independently by a drive control system for driving functional elements of the packing machine in a cycle time-synchronous manner during predefined motion sequences, one drive unit being a transverse sealing unit comprising a motor and two transverse sealing jaws for transversely sealing a film tube, the drive torque being measured using a drive controller, and the position of the drive motor measured using a position sensor, by removing the film tube from 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 at the target torque; and comparing the measured actual position to a target position stored in the drive control system and associated with the predefined target torque.

A tape layup apparatus whereby the tape layup performance on a surface to be laid up can be enhanced is provided, the tape layup apparatus being an ATL apparatus 10 having an ATL head 20 for laying up with pressing a tape 1 on a laid-up surface 2a, the ATL head 20 equipped with a pressing part 30 to press the tape 1 on the laid-up surface 2a and a parallel linkage 40 to operate in a manner that allows a pressing position and/or a pressing attitude of the pressing part 30 to follow a form of the laid-up surface 2a.

A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.

The invention is a device for welding two overlapping film sections situated on one side of a goods stack. The device includes a welding bar with a welding surface oriented in the direction of the film sections to be welded. The spacing between the welding bar and the film sections is reducible. The welding surface is elastically deformable into a concave course and/or to a convex course between its two ends. At least one displacing device adjusts the course of the welding surface to a concave and/or to a convex course. The displacing device displaces welding bar. A control unit of the welding bar individually controllable, such that the curvature of the welding bar is adjustable to the contour of the side of the goods stack in the region of the film sections to be welded with one another for the subsequent welding of the overlapping film sections.

An active anvil assembly for use in forming a looped suture is provided. The active anvil assembly includes an anvil member, a first sensor operably connected to the anvil member, and a control assembly. The first sensor is configured for measuring at least one of force, torque, and distance feedback. Also provided are systems and methods for forming a looped suture including an active anvil assembly.

A pair of thermoplastic resin members are placed on an anvil. A pressing force of a tool horn vibrating ultrasonically in a direction not perpendicular to but along upper surfaces of the pair of thermoplastic resin members is applied to the upper surfaces. The application of the pressing force of the tool horn vibrating ultrasonically allows melting of a vicinity of the upper surfaces of the pair of thermoplastic resin members. A welded structure part is formed on an unwelded structure part, thereby welding the pair of thermoplastic resin members as an overlap structure including the welded structure part arranged on the unwelded structure part. The distance and positional relationship between the pair of thermoplastic resin members after the welding are unchanged before and after the welding. The surfaces, placed on the anvil, of the thermoplastic resin members are neither burned nor discolored.

A system for controlled induction welding of at least one weld seam area (A) of at least two surfaces of at least one workpiece is provided. The system comprises an inductor configured to be arranged in conjunction with the at least one workpiece, a processing means configured to generate an electromagnetic field by applying an alternating voltage to the inductor so as to inductively heat at least one of the surfaces so that the weld seam area (A) is welded together, simultaneously measure at least one parameter (P) of the at least one workpiece at least based on the generated electromagnetic field, detect a change of the at least one parameter (P), and determine a temperature estimation of the at least one workpiece based on said detected change.
