Abstract: An apparatus for aligning electrical components with aligned connecting wires to form a belt between two adhesive tapes, the apparatus including a compact working member provided with a guidance and alignment arrangement for the second adhesive tape, (a) pressing device and a cutting device for cutting the connecting wires of the components. A pressing roll of the pressing device is rotatable, but rigidly mounted. Axially parallel grooves are provided in a circumferential surface of the roller, with the grooves being aligned with tooth gaps of the conveying gear wheels, thereby ensuring a better wrapping around of the connecting wires.

Abstract: An apparatus for working on the leads of electronic or electric components which is adapted to handle the components in a loose condition by way of a slide or in a bandoliered form. Bandoliered components have a regular spacing which is generally much smaller than the motion of tools in the direction of supply of the components, with the size of the motion being geared to the spacing between loosely supplied components. A tool group is moved backwards and forwards along the line of supply of the components, while the tools in the group are moved towards and away from each other. A limiting structure, which may be put into and out of operation, has the effect of overriding that is to say decreasing or completely stopping, the backward and forward motion of the tool group geared to the spacing of loose components.

Abstract: An apparatus for preparing leads for electrical components having a sliding guide with a guide slot for conveying the components, a cutting device for cutting the leads to length, and at least one tool set having two tools which are cooperable for shaping the connecting leads between them. At least one of the tools is operable to move against the other by a closing movement in a direction which is perpendicular to the guide slot, while both of the tools are jointly movable parallel to one another, in an operating movement, in such a manner that the closing movement of the tools set is synchronized with the operating movement so as to cause the tools to be closed during a part of the operating movement which takes place in a direction in which the components are conveyed and are opened in an opposite direction.

Abstract: An apparatus for working on the leads of electrical components has a component inlet or supply unit taking the form, for example, of a chute with a guideway opening, or with an inlet for the supply of components fixed to belts or paper tapes. The apparatus furthermore has two tools, each placed on a tool support. The two tools are moved together for forming the component leads, the leads being placed in the path of the tools. The tools are supported on a carriage, which may be moved in a direction parallel to the direction of input of the components. Furthermore, the tools are moved together in timed relation to input of the components and the working motion of the carriage.

Abstract: An apparatus for cutting to length and bending leads of electrical components has transport toothed wheels and bending toothed wheels, which are keyed on a common shaft and used with cutting tools and bending tools. Furthermore, there are gripping toothed wheels, acting with the bending toothed wheels, for stopping pulling forces acting on the components. Next to each bending toothed wheel, there is an arm, turningly supported on a further shaft and which is acted upon by a spring pulling it towards the main shaft. The gripping toothed wheels and the bending tool are supported on these arms. The apparatus designed on these lines may simply be retooled for different processing operations and in all cases makes certain that, on bending, the components are not acted upon by undesired pulling forces. The apparatus may be used for electrical components such as diodes, resistors and transistors, in the case of which the leads are generally in line and placed at the opposite ends of the components.

Abstract: Apparatus for stringing electrical components into a belt for convenience in handling, packing and despatch to customers, the components having two connecting wires extending in opposite directions and the belt comprising two runs of double adhesive tape to trap the connecting wires and incorporate the components into the belt in ladder-like formation. The components are fed down a guide and released one-by-one by a blocking slide to a transfer device comprising two rotating discs having slots for receiving the connecting wires and being associated, if necessary, with stationary projections for preventing them from falling out. The transfer discs may be associated with specially shaped rollers for straightening the connecting wires. The components then enter the actual belt make-up machine of the apparatus, comprising a pair of toothed wheels, each in two parts whose spacing is adjustable and each associated with a guide roller and a pressure roller.

Abstract: Apparatus for cutting to length the connecting wires of electrical components (such as resistors, capacitors, transistors or diodes) comprises a cutting device situated below a component guide which consists of a slideway defining a guide slot through which the connecting wires project downwardly. The cutting device comprises two shearing wheels which are arranged with horizontal faces thereof parallel and abutting one another in a region in which they overlap, the forward point of intersection of peripheral cutting edges of the wheel (the point at which cutting of the connecting wires commences) being situated below the guide slot. At least one of the wheels is driven and this has serrations at its periphery which are large in relation to the diameter of the connecting wires to be cut. The non-driven wheel is preferably of truncated conical shape widening towards the other wheel.

Abstract: An apparatus for cutting to length, bending and crimping the connecting wires of electrical components. The functions are provided by toothed wheels on a common shaft which transport the components and which co-act with cutting, crimping and bending tools. In order to ensure that after crimping, the components do not shift before the bending operation, the toothed wheels co-operating with the crimping tools are provided with radially arranged grooves which open into the bottom of each tooth space to engage the crimped wires and prevent rotation of the component about the wire axis.

Abstract: Apparatus for preparing leads of electrical components, such as transistors or the like, having a carrier plate rotatable about a fixed axis of rotation, at least one tool set arranged at the periphery of the carrier plate, said tool set including a stationary tool and a tool pivotable about a pivot axis that is parallel to the fixed axis of rotation, and a fixed cam disk. The pivotable tool, during rotation of the carrier plate, is controlled by an operating cam section of the fixed cam disk so as to move from an open position into a closed position, and the cam disk has a further, opening cam, section for controlling the pivotable tool so as to move from the closed position into the open position.

Abstract: Apparatus for mechanically processing (cutting to length, crimping and/or bending) the connecting wires of electrical components and being of a generally similar nature to that of U.S. Pat. No. 3,900,053. The present invention, however, provides for the various toothed wheels, which are mounted on a rotatable main shaft, to be readily removable for the purpose of exchanging them for others in order to adapt the apparatus to the processing of different components. To this end, the toothed wheels are mounted on sleeves on the main shaft and the latter has a bearing arrangement at one end which includes a detachable bearing plate mounted in a aperture in the apparatus housing, which allows the toothed wheels to be drawn off the main shaft over that end and through the aperture when the bearing plate is detached and the toothed wheels unclamped from the main shaft.

Abstract: A device is provided for automatically and continuously bending, crimping, and trimming the leads of electrical components having leads located on only one side of the component body. A vibrating supply container is provided which stores components and supplies the components to a conveyor. The conveyor transfers the components in sequence, one at a time adjacent one another in a groove to a transfer slot. A rotatable turning disc is provided adjacent the transfer slot which carries crimping and bending tools at the periphery thereof. The tools are arranged in pairs, with one of the tools being pivotally mouned at the carrier disc and the other being relatively fixedly mounted. The relatively fixedly mounted tool is disposed so as to grip a component in the transfer slot as the carrier is rotated thereby, while the pivotally mounted tool subsequently is pivoted into crimping engagement with the leads as the carrier continuously rotates.

Abstract: In an apparatus for mounting electrical components having connecting wires extending outwardly from opposite ends thereof in a belt by locating each such wire between a respective pair of superimposed bands, the toothed, transport wheels and rollers to which the bands are fed and at which such bands are combined with the wires interposed therebetween are axially adjustable to provide for the ready use of the apparatus in the context of components of a range of dimensions, the tape-feed arrangements similarly being adjustable to maintain their alignment with a respective roller.
