摘要： Sheet nails (2) made in a metal strip (1) and connected to each other in the strip via connecting bridges (3) are oriented at an angle or perpendicular to the longitudinal direction of the strip (1). The sheet nails have a profiled shank (4) and a profiled head (5) at one end, as well as an edge, a point or several laterally spaced points (6) at the opposite end of the shank. The shank is connected to the head (5) via a transition portion in the form of a gently curved bent portion (7). The head (5), the shank (4), and the bent portion (7) have preferably a uniform cross-sectional shape. The head, the transition portion and at least a portion of the shank can also have an extra reinforcing profile in addition to the common profile in these portions.

摘要： Method and device for moving a tool (8) to a desired posi­tion relative to and in engagement with an incrementally advanced strip of material (10) held in place during the work stroke of the tool and having a repeated basic shape. Between the advancements, the strip (10) is held longitu­dinally stationary, so that the tool can be engaged by a movement across the strip, without moving it therealong. The tool is finely adjusted relative to the basic shape by a movement to the correct engagement position steered by at least one basic shape sensor (36) connected to and spa­ced from the tool along the strip. To control the tool, the basic shape sensor is caused to locate the exact posi­tion of one (48) basic shape at one or more basic shape spacings from the basic shape (50) to be engaged by the tool (8). The sensor brings with it and steers the tool As it moves to locate the exact position, the sensor brings with it and steers the tool. The work stroke of the tool perpendicular to the strip is triggered only when the sen­sor has reached said exact position. The device comprises a tool bed (2) with die means (42,44), a slide (4) slide­ably mounted on the bed with a tool holder (2) carrying the tool spaced from the die means. Between the tool and the die means there is a space for incremental advance of the strip. The tool holder (20) carries the basic shape sensor (36) which is mounted spaced from the tool and locates the exact position of said basic shape (48) spaced from the basic shape (50) to be engaged by the tool. The tool is finely adjusted relative to said basic shape by the position locating movement of the sensor bringing the tool with it along the length of the strip.

摘要： An arrangement for profiling forwardly indexed material webs for producing e.g. parallel, transverse undulations in a sheet metal web (6) of uniform width which is forwardly indexed through a forming space (5) located between a lower bed (1) having a die (3) with an upwardly turned forming surface (4, 21) above which is a holding device (8) carrying a punch mechanism (7) reciprocatingly driven relative to the die (3) and executing a forming stroke while engaging the web and the forming surface of the die. An inclined ramp (22) guides the incoming web obliquely downwards towards the forming location (21) on the forming surface. Close to the ramp is a web support body (20) yielding transversely to the plane of the ramp when the web is stretched over the body during profiling by the forces of the punch mechanism (7) located beneath (9) the holding device which is formed as an attachment plate (8) movable in relation to the bed (1) and has a punch tool (10) extending from the plate (8) and a holding punch (12) axially movable along the punch tool and mounted on guide means (13) attached to the plate (8) and held forwardly biased in an outwardly protruding position by spring devices (16) acting between the plate and the holding punch.

摘要： The invention relates to an arrangement for advancing a continuous strip of mutually integrated nails to the nail driving section (5) of a nail driving apparatus provided with a safety-catch device (24) and a nail strip magazine, and to hold the nail strip in the nail driving section. Single nails are stripped from the nail strip in the nail driving section by means of percussion and driven, in con­junction therewith, into the workpiece to be nailed. The magazine (6) incorporates a nail strip accommodating strip guide path (7) which adjoins the nail driving section (5) and in which the nail strip is held biassed towards a nail driving location in the nail driving section (5) by strip feed means (17, 18) located adjacent the strip guide path and engaging the nail strip located therein. The nail driving location is constructed in a manner to prevent a lone, unattached nail from twisting or turning therein. For the purpose of positioning the foremost nail in the nail strip in an exact position in the nail driving loca­tion (this foremost nail being the next in line for sepa­ration/driving into the workpiece) there is provided a rotatable nail positioning element (35) which is journal­led for rotation and sideways movement in the nail driving section (5) and which is capable of being brought into engagement with the nail strip. The safety-catch device (24) is movable relative to the nail driving section and is held in a forward safety position by means of a coil spring. The safety device presents a latching surface (31) in the region of the positioning element (35), and arran­ged between the latching surface and the nail positioning element is a movable latching element (38). As the safety-­catch device (24) is retracted (to its nail firing mode) the latching surface (31) is urged against the spherical latching element (38), which in turn moves the nail posi­tioning element (35) into position-fixing latching engage­ment with the nail strip, in a region thereof immediately behind the foremost nail located in the nail driving loca­tion.

摘要： Des agrafes plates (2) obtenues à partir d'une bande métallique (1) et reliées entre elles en bandes par l'intermédiaire de ponts de liaison (3) sont orientées suivant un angle ou sont perpendiculaires par rapport au sens longitudinal de la bande (1). Les agrafes plates présentent une tige profilée (4) et une tête profilée (5) à une extrémité, ainsi qu'un bord, une pointe ou plusieurs pointes espacées latéralement (6) à l'extrémité opposée de la tige. Celle-ci est reliée à la tête (5) par l'intermédiaire d'une partie de transition ayant la forme d'une partie à courbure douce (7). De préférence, la forme de la section transversale de la tête (5), de la tige (4) et de la partie courbée (7) est uniforme. La tête, la partie de transition et au moins une partie de la tige peuvent également présenter un profil supplémentaire de renforcement en plus du profil commun desdites parties.
