Ring-forming tool (1) for closing a ring (19), which comprises a top piece (2), a bottom piece (3), a top claw (4) and a lever (9), connected together by means of four pivot points (7, 8, 17, 18), three of which present a fixed position and one of which presents a variable position that enables the tool (1) to vary the lever arm and therefore vary the force exerted on the ring (19) for a same force exerted by the user. In this way, the inventive tool may provide decreasing forces on the ring (19) as the ring (19) closes and offers less resistance.

The plier-staplers of the patent include a slide or store of staples which is kept at the height of the stapling claws in order to feed a staple to these claws and straight afterwards the staple slide withdraws automatically from the stapling area so as to allow the staples to be placed perfectly. Once that the operation has been performed, the slide returns to its position for feeding staples to the claws of the pliers. This is archieved by turning piece (5) which is connected to the staple slide (7) which, when activated by control (13), is withdrawn, and after stapling returns to its initial position thanks to the action of the spring (12).

New heads adapted to a tape stapler machine in order to carry out all kinds of tightening binding and stapling operations, not only for props, guides, canes or bunches or bundles of twigs or branches, but also any group of parts or items that require a certain binding tension so that they become well fitted or adjusted to each other, with the binding creating a certain reactive force, for which a type of tape is used which has a degree of elasticity capable of supporting the increase in the reactive tension of the bound bundle and to give rigidity and robustness to the binding.

A converter device for staple-stitching pliers for fixed or retractable operation of the staple slide, applicable to staple-stitching pliers of the type covered by European Patent application 86.500 002.0, so that the said pliers can have the slide-holder part and the staple slide either in the fixed position or in the rotatable position. To do this, there is a shaft (23) housed in a bushing or sleeve (24) and this in turn is inside an external control (13). The shaft (23) is controlled by a spring (22) in a head (21). The end of the shaft (23) juts out or remains hidden in the interior.
摘要:
A process for tying metal reinforcement and/or mesh structures wherein U-shaped clips having bent and generally diverging arms are placed at the crossings of the rod to be tied together and engage twice on each of the rods of the crossing, the arm ends being closed by being twisted until a portion of the ends ruptures, the twisting being performed by a substantially longitudinal tool having at the front jaws which in the open state close on the clip ends, turn and twist the same and finally break the ends leaving them twisted, the jaws returning to the same initial position.

Device (1) for the assembly of false ceilings, insulation panels in ceilings and other types of suitable panels, which comprises a main body with a U-shaped section, with an intermediate face (2) and two side faces (3), the side faces (3) being disposed with grooves (5) for the insertion of guide flaps (6) of a profile (7) associated or attached to the false ceiling, insulation panel or any other type of suitable panel, where the device (1) is characterised in that the side faces (3) partially face each other, with the result that the intermediate face (2) is substantially a non-rectangular parallelogram. This shape of the device (1) enables its assembly on the profile (7), the assembly being completed by means of merely moving and turning the device (1) between the guide flaps (6) of the profile (7).

摘要:
Staple (1) for tying a plant stem or branch to a guide element (8), string or similar, where the staple (1) is formed of a thin metal rod, bent until it presents a specific form that enables an independent clamping of the guide element (8) and of the branch, with the advantage that the design of the staple (1) is valid for applications with guide elements (8) of different thicknesses or diameters, from tapes or thin strings to thick strings and even poles. To achieve this, the staple (1, 1') presents a convex projection (4, 4') formed on its central part (3) and which may present various sizes. An interior cavity (6, 6') located in the convex projection (4, 4') may remain or not when the staple (1, 1') is closed.
