Method and device for manufacturing a profile member of composite material, the cross-section of which has three branches, including the steps of: —moving together two opposite edges of a panel (2) of sheet material in such a manner that these two opposite edges are juxtapositioned in one juxtapositioning direction; translating a pair of jaws (20) in a direction perpendicular to the juxta-positioning direction in such a manner that the pair of jaws (20) is positioned on either side of the opposite juxtapositioned edges, this translational movement of the pair of jaws (20) being carried out in the direction of a base (25); —simultaneously pressing the sheet material between the two jaws (20), on the one hand, and between the jaws (20) and the base (25), on the other hand; —finishing the profile member of composite material by hardening with a matrix with which the sheet material is impregnated.

A non-compliant fiber-reinforced medical balloon comprises a first fiber layer and a second fiber layer embedded in a continuous matrix of thermally-weldable polymer material defining a barrel wall, cone walls and neck walls. The fibers of the first fiber layer have a pattern of different lengths and are divisible into a first group and a second group based on length. The length of the fibers of the second group varies progressively in accordance to their proximity to the fibers of the first group; the fibers of the second group closest to the fibers of the first group being longer than the fibers of the second group further from the fibers of the first group. The fiber of the second fiber layer winds circumferentially around the longitudinal axis of the balloon substantially over the entire length of the balloon.

A controlled shear vacuum forming method that includes forming a three-dimensional (3D) structure from a preform material on a molding tool using restraints during vacuuming to prevent wrinkling. The restraints are withdrawn during vacuuming to allowing the preform material to come into contact with the sidewalls of the molding tool in a gradual manner. Such forming method is particularly suitable for forming wing spars with bent sections and/or curved contours.

Air duct for distributing air in a greenhouse, the air duct comprising a hollow main body extending along a longitudinal axis and at least one set of vents, wherein the main body has an outer surface and an inner surface, a first end and a second end at the opposite longitudinal ends of the main body, and a segment disposed between the first end and the second end extending over substantially the entire length of the main body, wherein the cross-sectional area of the main body in this segment decreases towards the second end, wherein the vents belonging to a respective set of vents are distributed at intervals over substantially the entire length of said segment, and wherein at least said segment of the main body is made from plastic.

A firearm holster includes a plate that is folded to form a cavity. The cavity is defined by a first sidewall, a trigger sidewall adjacent to the first sidewall, a second sidewall adjacent to the trigger sidewall, a barrel sidewall adjacent to both the first and second sidewalls, and a muzzle end wall. The muzzle end wall is adjacent to the first sidewall, the trigger sidewall, the second sidewall and the barrel sidewall. The firearm holster also includes a support wrap that at least partially surrounds the cavity and is fused to one or more of the first sidewall, the barrel sidewall, and the second sidewall.

A method for manufacturing a blood pressure information measurement apparatus includes the following steps: forming a hole in a flexible resin sheet; inserting a connecting pipe into the hole; overlaying a first end portion and a second end portion of the flexible resin sheet such that an inner side of the first end portion contacts an outer side of the second portion; welding a location at which the first end portion and the second end portion overlap to form a first welded portion, such that the flexible resin sheet forms a tube-shaped body having a first end and a second end; flattening the tube-shaped body; welding the first end and the second to form two second welded portions, such that the tube-shaped body forms a bladder having two long sides and two short sides; and welding portions of the resin sheet which overlap along a first long side to form one or more partial welded portions.
