A method of manufacturing an armour layer of a flexible pipe for transporting fluid from a subsea location and apparatus are provided. The method comprises winding a first length of composite tape to form a first section of the armour layer and positioning an end region of the first length of composite tape over an end region of a second length of composite tape to form an overlapping tape section. Heat and pressure is applied to the overlapping tape section to form a joined overlapping tape section in which the first length of tape is joined to the second length of tape such that the joined overlapping tape section has a lap shear strength of at least 11 MPa. The joined overlapping tape section and the second length of composite tape are wound to form a second section of the armour layer.

A method of anchoring a connector in a first object, wherein the first object is a lightweight building element having a first outer building layer and an interlining layer, and wherein the connector includes thermoplastic material in a solid state. The method includes: bringing a coupling surface portion of the connector into contact with an attachment location of the first outer building layer; displacing a portion of the first outer building layer at the attachment location with respect to the interlining layer by applying a first pressing force to the first outer building layer and thereby piercing the first outer building layer; applying a second pressing force to the connector and transferring energy to the connector until a flow portion of the thermoplastic material has liquefied and flown to interpenetrate structures of the interlining layer; and stopping the energy transfer and allowing the flow portion to re-solidify.

A method for connecting first and second plastic parts by a laser transmission bonding wherein the first plastic part absorbs laser light and the second plastic part is made of transparent plastic. The method includes the following steps: positioning the first plastic part in a first tool, positioning the second plastic part in a second tool so that the first plastic part and the second plastic part are spaced from each other thereby preventing mutual heat exchange between the parts, directing laser light through the second plastic part onto a connection zone of the first plastic part whereby the first plastic part is heated at least within the connection zone, after heating the first plastic part, moving the second plastic part into contact with the first plastic part, so that the second plastic part is firmly bonded to the first plastic part.

The present invention provides, in various embodiments, a rotary-type machine (M) for continuously sealing individual foil bags (B) by way of ultrasonic welding between an anvil (6) and a sonotrode (5) in at least one welding station (S) of a carousel (1), where each foil bag (B) can be positioned by way of holders (11). In some embodiments, the rotary-type machine (M) comprises at least one welding station (S) composed of a sonotrode (5) being located stationary at least relative to the direction of circulation (8) and anvils (6) which with intermediate spacings (7) rotate past said sonotrode (5) successively in the direction of circulation (8) of the carousel (1). According to the invention, the foil bags (B) are sealed at the stationary sonotrode (5) when the anvils (6) equipped with the foil bags (B) are rotated past.

A method and a device are disclosed for making thin plastic films having two or more layers, which are subdivided and separated in the form of tubular bags for portioned reception of different products, wherein the plastic films are provided with welding seams running substantially transversely to the longitudinal direction with predetermined spacing between one another to form bag-like containers, and the containers are separated from one another by a cutting or separating process, the method being characterized by the steps: a) welding the films with predetermined spacing by means of an ultrasound welding process, maintaining a defined, film-dependent distance between a processing tool and a counter tool while welding; and b) separating the tubular bags welded in this way by means of a mechanical cutting process, with or without reduced ultrasound excitation at the point of the respective weld seams.

A device for assembling plastic objects including caps for coupling to base support at least partially counter-shaped to the cap. The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

The invention relates to a sealing station in a film bag filling device for sealing of film bags after a filling process, wherein the sealing station comprises a first and a second sealing arm for sealing of several filled film bags that are arranged next to one another, wherein the first sealing arm is moveable with a first drive shaft and the second sealing arm with a second drive shaft. A servo engine is disposed on the first drive shaft, and a drive movement of the first drive shaft from a first gear wheel is transferred to a second gear wheel that encroaches in the first gear wheel and from the second gear wheel to the second drive shaft. The invention further relates to a method for sealing of film bags after a filling process with the sealing station according to the invention with the following steps: positioning of filled film bags below the sealing station; closing of the sealing arms and application of a contact pressure with a first value and sealing of the filled film bags.
