A method for producing composite profiles comprises providing a first profile part extending in a longitudinal direction, made from a first plastics material, with a profile region produced from a second plastics material thermally plasticizable at a first temperature, providing a second profile part extending in a longitudinal direction, made from a material not thermally plasticizable at the first temperature, and with a receiving structure formed along the longitudinal direction of the second profile part, with which the profile region of the first profile part is connectible, bringing the profile region of the first profile part into contact with the receiving structure of the second profile part, plasticizing the second plastics material of the profile region by heating to the first temperature and deforming the plasticized profile region while forming a positive engagement between the profile region and the receiving structure while maintaining the geometry of the receiving structure.

A method for performing a task in registration with a discrete seal in at least one material is described herein. The method involves simultaneously forming a discrete seal and a fiducial/eye mark in the at least one material. The method includes providing a detection device; providing a unit operation mechanism; and performing an operation on the material(s) in registration with the discrete seal. The task performed in registration with the discrete seal is based upon the location of the eye mark that was simultaneously formed with the discrete seal. A method of making flexible containers using cutting to form the outer periphery of the packages is described herein. Also described herein are flexible containers and container blanks made by such a method.

An additive manufacturing apparatus for manufacturing a three-dimensional object comprises a layer application device (16) for applying a building material layer by layer, an energy input unit (20) which comprises a carbon monoxide laser (21) and a radiation supply unit for supplying laser radiation of the carbon monoxide laser to positions in each layer that are assigned to the cross-section of the object in this layer, and a laser power modification device (27) adapted to effect an increase of the power per unit area incident on the building material within a time period that is smaller than 300 μs and/or larger than 50 ns, when the laser power is increased and/or to effect a reduction of the power per unit area incident on the building material within a time period that is smaller than 100 μm and/or larger than 100 ns, when the laser power is decreased.

A method for plasma treating a surface of a first substrate is disclosed. The method may comprise generating a plasma flume using a plasma treatment device having a nozzle. The plasma flume may emanate through a flume aperture of the nozzle at an emanation angle of about 5 degrees or less. The emanation angle may be defined as an angle between a central axis of the nozzle and a central axis of the flume aperture. The method may further comprise plasma treating the surface of the first substrate with the plasma flume by scanning the plasma flume over the surface of the first substrate. The first substrate may be one of a consolidated thermoplastic material and a cured thermoset material.
