A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.

The invention relates to a profiled plastic section (1) for a metal/plastic composite profiled section (31). The profiled plastic section (1) comprises a first profiled element (2) and at least one second profiled element (3). The first profiled element (2) and the second profiled element (3) together form a latching mechanism (4, 9; 5, 10; 6, 11), by means of which a form-fitting connection can preferably be produced between the first profiled element (2) and the second profiled element (3) in a width direction (x) and in a height direction (y). The first profiled element (2) and the second profiled element (3) overlap preferably over a large area when the form-fitting connection is produced between the first profiled element (2) and the second profiled element (3), and the form-fitting connection can be produced on the cross-sectional plane (x, y) between the first profiled element (2) and the second profiled element (3) by latching the profiled elements (2, 3) of the profiled plastic section (1). The form-fitting connection between the first profiled element (2) and the second profiled element (3) is designed such that a movement of the first profiled element (2) and the second profiled element (3) in a longitudinal direction (z) of the profiled plastic section (1) is allowed when a first metal component (29) is connected to the first profiled element (2) and a second metal component (30) is connected to the second profiled element (3) preferably in a shear-resistant manner. The profiled plastic section (1) can likewise also be designed with more than two profiled elements (2, 3), and the basic principle according to the invention of generating a shear-free plastic/metal composite profiled section (31) can be carried over.

An insulating body for multi-shell construction elements for spacing apart and thermally separating at least two profiled section elements relative to each other has a base member with a first side and a second side opposite the first side. Fastening projections are arranged on the first and second sides of the base member and secure the insulating body in receptacles of the profiled section elements. At least the first side has two of the fastening projections. The base member has a hollow chamber with an inner guiding contour for receiving and guiding fitting parts. A multi-shell construction element with at least two profiled section elements is provided with at least one such insulating body.

A composite architectural frame section with subcomponents that meet functional, strength and thermal isolation requirements is assembled using knurling and crimping operations as joining procedures. When properly designed the knurling and subcomponent geometries with proper crimping operations result in an optimal shearing strength between critical subcomponents, thus maximizing the structural performance aspect of the frame section. Various embodiments of this design address requirements for subcomponent features such as: hammer and anvil tips, orientation of knurled and crimped surfaces, design of the knurling wheel components, and the introduction of alternate surface topographies to additional regions of these contacting frame subcomponents. These embodiments serve to maximize the portion of available interface contact surfaces and their friction that can bear shearing forces and, thus, add to the overall shear strength of the frame section.

A window includes a vacuum insulating glass (VIG) window unit in a window frame. The window frame includes at least one vacuum insulated structure (VIS) for improving the insulating functionality of the frame, so that the frame can adequately insulate the periphery of the VIG unit. Such windows may be used in residential and/or commercial window applications for buildings. The use of a window frame having at least one VIS is advantageous in that allows for improved window frame thermal performance and a narrow frame design if desired for improved aesthetics.

An insulating strip (3) connects profiles (2) of a composite profile (1) for doors, windows or faade elements. At least one of the profiles has a roll-in groove (6) and is composed of a first metal material. The insulating strip (3) includes a strip body (4) composed of an insulating material and extending in a longitudinal direction (z). A roll-in head (5) is formed at a longitudinal edge of the strip body (4). The roll-in head (5) has a cross-sectional shape in a plane (x-y) perpendicular to the longitudinal direction (z) suitable for insertion into the roll-in groove (6). A metal sheet (13) having surface variations (17; 18) covers at least a portion of a surface (10, 11, 12) of the roll-in head (5). At least a portion of the sheet (13) is composed of a second metal material having a tensile strength of 300 N/mm.sup.2 or more.

Machine (1) for the assembly of profiles (2) formed of at least a first profile section (3) and a second profile section (4) connected by means of one or several thermally insulating sections (5,6), whereby the machine (1) is provided with press means (58) exerting an adjustable pressure on press tools (48) in a lateral direction (HH) and towards the profile sections (3,4) to be assembled so as to be able to exert an adjustable force on corresponding walls (18) of grooves (17,20,31,33,82,90) of the profile sections (3,4) in order to achieve a plastic deformation thereof.

A composite profile for windows, fixed glazing, faades, doors or glass roofs. A metal profile is produced by shaping, in particular by roll-forming, from a sheet metal material and that has a profile cross section that forms a groove and a web, the web being formed by profile portions that are on top of one another at least in portions and transition into profile portions that define the groove. The composite profile further comprises an integral or multi-part insulating profile received in the groove of the metal profile in portions and is non-positively and/or positively connected to the metal profile. The insulating profile and/or a further profile received in the groove of the metal profile engages/engage in pockets of the metal profile that are open towards the groove and are arranged on either side of the web.
