METHOD FOR MANUFACTURING LONG MEMBER
A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.
APPARATUS AND METHOD FOR BENDING TUBULAR PRODUCTS
Apparatus (10) for bending tubular products (100) wherein each tubular product (100) is provided with a flexible portion (111) configured to allow a bending of the tubular product (100). The tubular products (100) are disposed, at least temporarily, on positioning means (19), while bending means (18) each allow the bending of a respective tubular product (100) in correspondence with the flexible portion (111).
System and method for manufacturing fittings and connections for biaxially-oriented plastic pipes
The present invention discloses a system and a method for manufacturing fittings and connections for biaxially-oriented plastic tubes in an integral way from straight preformed tubes, with the possibility of adjusting and distributing the thicknesses as well as adjusting the specific stretching in the different areas of the fittings, allowing them to be reinforced or optimized during the method itself and without causing an increase in the production time or an increase in the raw material used, such that it allows for the manufacture of fittings of different geometric shapes (curves, tapers, couplers, branches, etc.)
PREFORMED THERMOPLASTIC TUBE INCLUDING AT LEAST ONE BEND
A method for making a preformed thermoplastic tube having a tube wall and including at least one bend formed by thermoforming, characterized in that on an inner curve of the bend the tube wall is provided with a pattern of corrugations with minimal dimensions in terms of number of and heights of corrugations such that a wall length reduction resulting from the corrugations along the inner curve is kept at a minimal value necessary to absorb overlength on the inner curve resulting from forming the bend, and in that on an outer curve of the bend the tube wall is smooth and free of corrugations.
METHOD FOR MANUFACTURING COMPOSITE STRUCTURE, AND LAMINATE
The purpose of the present invention is to further enhance the strength of a manufactured composite structure by further suppressing the occurrence of wrinkling. A method for manufacturing a composite structure, the method comprising: a lamination step for layering a plurality of fiber sheets and molding a plate-form laminate; a forming step for forming a recess formed by a curved surface in a prescribed portion of the laminate; a short-direction deformation step for deforming the laminate in the short direction thereof after the forming step to configure a long-direction cross-section of the laminate in a prescribed shape; and a long-direction deformation step for deforming the laminate in the long direction after the forming step, so that the recess formed in the forming step deforms, to configure a short-direction cross section in a prescribed shape.
TUBING BENDER
A compact, lightweight, portable tubing bender configured to enable one-handed operation. The tubing bender includes a portable housing including a handle portion, a bender shoe operably coupled to the portable housing, the bender shoe defining an arcuate channel configured to restrain a length of tubing along a prescribed arc during bending operations, a guide gear fixedly coupled to the bender shoe, and a guide frame pivotably coupled to the bender shoe, the guide frame including a motor, a driven gear and a guide member, the motor configured to drive the driven gear along the guide gear to pivot the guide frame relative to the bender shoe, so as to move the guide member during bending operations to guide the length of tubing along the arcuate channel of the bender shoe.
COIL CATHETER METHOD OF MANUFACTURE
A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.
Curved catheter and methods for making same
A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.
THE APPLICATION OF THE 3D CAMERAS TO THE PROFILE BENDING PROCESS ON THE BENDING MACHINE WITH THREE AND FOUR ROLLERS
The application of the 3D cameras during the profile bending process on the bending machine with three and four rollers provides controlled management, regulation of control as well as correction of the bending process, where the application of the 3D cameras (1) and (2) provides a three-dimensional view of the bending process and each point of interest on the machine (3) and on the profile (4) is defined dimensionally and in space. Utilizing the 3D cameras (1) and (2) during the bending process the profile (4) is detected, thus implementing a feedback loop between the computer (7) controlling the bending process and the profile (4) bent on the machine (3). The feedback loop created with the application of the 3D cameras (1) and (2) provides information regarding the profile (4) bending process on the machine (3) and based on this information the computer (7) is able to manage, regulate and correct initiated profile (4) bending process in order to receive desired output at the end of the bending process, that is, the profile (4) bent to the pre-determined angle, radius or diameter.
Tapered implantable device and methods for making such devices
A tapered implantable device includes an ePTFE tubular member having a tapered length portion. The tapered length portion provides rapid recovery properties. The tapered length portion can feature a microstructure that includes a multiplicity of bent fibrils.
