An apparatus and method of closing a wide variety of thermoplastic tubes, in particular with Shore hardnesses of around 50 (A) to above 100 (A), where the tubes having inside diameters of 1.6 mm to 35 mm and/or wall thicknesses of 0.8 to 4.8 mm. The method involves use of a tube heater having at least one heating element. The heating element has at least four heatable regions which are movable with respect to one another. The tube heater is configured to enclose, in the applied state, at least 75% of the circumference of the tube while bearing against the latter over its circumference at at least four points which are spaced apart from one another. One of the key advantages is that, prior to compression, the tube can already have been heated at a plurality of points on the tube.

A method for the production of a suction jet pump delivering fuel into or out of a fuel tank, wherein the suction jet pump has a flow channel and a nozzle, and wherein the flow channel forms a feed line to the nozzle and the flow channel is formed in one piece with the nozzle, the method including, in the following order: placing a mold core into a matrix to produce the suction jet pump by injection molding and form a cavity between the mold core and the matrix; encapsulating the mold core and filling the cavity formed between mold core and matrix with a plastic; removing the mold core through an installation opening, arranged opposite the nozzle, in the flow channel; and closing the installation opening by thermal deformation, in the edge region of the installation opening, of the plastic used for the production of the suction jet pump.

A method of manufacturing an irrigation implement may include receiving tubing. The tubing may be conventional plastic irrigation tubing. The tubing may be cut to form a first end of an irrigation implement. The tubing may be cut to form a second end of the irrigation implement. Either the first end or the second end of the tubing may be pinched in forming the irrigation implement. The pinched end of the tubing may be sealed in forming the irrigation implement. In an embodiment, the pinched end may be heat sealed to form the irrigation implement.

A machining method and coupling structure for a fiber reinforced plastic structure member (1) obtained by narrowing an end of the member (1). Also included are a reinforcing member (4) which inhibits expansion by adhering to the outer circumference of the narrowed portion of the fiber reinforced plastic structure member, a locking member (2) which is provided with a through-hole (2a) in an axial direction and which fits into a narrowed portion (1a) of the fiber reinforced plastic structure member 1, a coupling anchoring member (3) which is provided with a rotation stop on the side thereof, and a spacer (5) which restricts only a rotation of the coupling anchoring member (3) and which is attached between a member (7) to be coupled and an end of the fiber reinforced plastic structure member (1) by passing the coupling anchoring member (3) through so as to slide in the axial direction.

An irrigation implement including a member having a first end and a second end, the first and second ends both being positioned along a longitudinal axis of the member. The first end being open and the second end including a pinched seal. The member further defines an opening disposed toward the second end, and being configured to enable an irrigation tube to be attached to the opening such that the opening is sealed by the irrigation tube.
