Depth control of seal line penetration for rotary ultrasonic horn/anvil welding without mechanical stop

An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.

SYSTEMS AND METHODS FOR SEALING A CONTAINER

Systems, apparatuses, and methods to seal a container are provided. An apparatus for securing a film to a container includes a body portion to house film and a sealing portion. The sealing portion includes a loading zone to receive a portion of film from the body portion and an aperture to receive a top portion of the container and the portion of the film therethrough to enable positioning within a sealing volume. A plurality of near-infrared light emitting diodes (NIR LEDs) face toward and at least partially surround the top portion of the container when positioned within the sealing volume. A controller is configured to receive sensor input from a sensor indicating that the top portion of the container is within the sealing volume and cause, in response thereto, activation of the plurality of NIR LEDs to secure the portion of the film to the top portion of the container.

Waveguide segment for plastic welding, arrangement for plastic welding, a welding method as well as a manufacturing method of a waveguide segment

A waveguide segment with two sub-segments including a first sub-segment with a first wall and a second wall, each having an inner face by which laser light can be reflected. The inner faces are opposite to each other and a depth of the sub-segment is defined by a distance between the first and the second inner face. Further, each wall has an exit side, and an opposite entry side, a height defined by the distance between the exit and the entry side and a width. At least part of the entry side of each wall extends in an angle to the height, for which applies: 0°<α<90°. The second sub-segment may be formed complementary and the second sub-segment has a portion at the exit side of each wall. Laser light passing through the second sub-segment enters the first sub-segment between the first and the second portion.
