20230323682 · 2023-10-12 ·

Scaffolding element (100) with insulation, said scaffolding element (100) comprising a frame (110) of metal braces (111) and a set of fastening means (120), arranged to fasten the scaffolding element (100) to a supporting structure (20) of a scaffolding structure (10).

The invention is characterised in that the scaffolding element (100) furthermore comprises a block (130) of insulating material, and in that the block (130) is cast around the frame (110), so that the frame (110) is completely covered by said insulating material but so that the fastening means (120) are not covered by said insulating material.

The invention also relates to a manufacturing method and a kit of parts.

THERMOPLASTIC ARTICLES HAVING PRECISE MICRO-SCALE FEATURES AND LONG-RANGE MACRO-SCALE REPRODUCIBILITY

A variety of thermoplastic parts are provided with precise micro-scale features and long-range macro-scale reproducibility. By combining the advantages of rigid tool molding and soft tooling into a hybrid tooling, complex and challenging microfeatures can be created in thermoplastic parts with remarkable positional accuracy and reproducibility. The parts described herein can demonstrate orders of magnitude smaller inter-part variations and order of magnitude smaller variations with respect to a master part as compared to conventional hard and soft tooling methods. In some aspects, a plurality of thermoplastic parts having precision micro-scale features and reproducible macro-scale dimensions are provided wherein the precision micro-scale features on each part comprise at least one challenging microfeature; and wherein a mean normalized displacement of the micro-scale features is about or less when measured between the parts in the plurality of thermoplastic parts.

PULSE WELDING METHOD AND WELDING TOOL FOR PULSE WELDING FOR A MEDICAL PACK FORMED AS A BAG
20230294366 · 2023-09-21 ·

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

20230294169 · 2023-09-21 ·

An object of the present invention is to propose a bending die capable of creating a product without causing buckling, even if the shape of the product is long or bent freely in three-dimensional space. The bending die according to the present invention is a bending die having a smooth shape formed by virtually and continuously moving, in three-dimensional space, a profile including a substantially circular-shaped first closed curve having a recess portion, wherein an opening width b of the recess portion is shorter than a groove width a of the recess portion, a tube insetting portion is formed by the recess portion, and the smooth shape is realized and created in real space using a three-dimensional printing technique.

Method and apparatus for making bags

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.
