Abstract: A hand-held blind rivet riveting tool includes a housing and a drawing element mounted within the housing. The drawing element is movable in a drawing direction relative to the housing. A first grip lever is pivotable about a first pivot point relative to the housing. A second grip lever is connected to the housing. A connecting rod mechanism is disposed between the first grip lever and the drawing element. The connecting rod mechanism has a variable transmission ratio.

Abstract: A blind-rivet setting device, includes a tension device, an intermediate storage and computing device, an evaluation device and an electrical circuit. The tension device is driven by an electric motor having an input current and provides a tensile force on the blind-rivet. The intermediate storage and computing device stores and computes a rated current range depending on the material and dimensions of the blind-rivet. The evaluation device has a comparator for monitoring the input current received by the electric motor. The electrical circuit produces an error message when the maximum value of the input current is not within the rated current range.

Abstract: A blind fastener setting device includes a drawing mechanism and an adjustably supported tip piece. The tip piece has several mandrel guide channels, each of which can be aligned with respect to the drawing mechanism. The tip piece can be easily adjusted without the overall size of the device having to be enlarged to any significant extent. The tip piece has a cross-sectional shape of a polygon which has an uneven number of sides. The mandrel guide channels each extend from a side to the oppositely disposed corner.

Abstract: A blind rivet includes a mandrel shaft having a head disposed at one axial end. A hollow rivet shell has a cylindrical shape including an inner cylindrical surface and an outer cylindrical surface. The rivet shell surrounds the mandrel shaft. The outer cylindrical surface has at least one attenuation groove, which includes at least two recesses. Each recess has a bottom surface that substantially forms a secant with respect to the outer cylindrical surface. A method of manufacturing a blind rivet comprises the steps of placing a mandrel shaft having a head within a hollow rivet shell, producing at least one attenuation groove in an outer cylindrical surface of the rivet shell after the placing step so that at least two recesses are formed. Each of the recesses has a bottom surface that substantially forms a secant with respect to the outer cylindrical surface.

Abstract: A power tool for the setting of blind rivets has a reversible electric motor which can reciprocate a gripper for the mandrel of a blind rivet through a transmission employing a rotary nut driven by the motor and a spindle which reciprocates the gripper in response to rotation of the nut. The motor is permanently connected with the spindle, and hence with the gripper, and the ratio of the transmission including the nut and the spindle is not dependent upon the position of the gripper. Such construction enhances the comfort to the operator of the power tool. The electric circuit for the motor is designed in such a way that the motor is disconnected from a portable energy source and is braked prior to a reversal in the direction of rotation of its output element.

Abstract: A blind riveter has a T-shaped housing whose one T-arm forms a working tip provided with a reciprocal internal chuck, whose other arm is formed as a hollow compartment, and whose central T-leg incorporates a pneumatic cylinder. The cylinder can displace the chuck to pull the mandrel of a blind rivet, thereby pulling the rivet back against the tip to upset the rivet. A passage extends from the chuck back into the compartment. The cover of the compartment is formed with a jet pump that is powered off the pneumatic supply that operates the riveter and serves to suck a mandrel pulled from a rivet back from the chuck into the compartment.

Abstract: A tool for setting internally threaded blind-rivet nuts comprises a pliers-type structure having a fixed arm having at one end thereof a hammerhead housing formed with a bore in which a pulling piece is linearly guided. A mandrel having an external threaded part for screwing into a blind-rivet nut removably clamped in this pulling member and can be dislodged by forcing it through the pulling member and out of the end remote from the end of the head at which the blind-rivet nut is to be set. The housing is formed with a stop screw which can be indexed in place to limit the displacement of a movable arm on the housing which arm is connected with the pulling member and establishes the stroke thereof.

Abstract: A blow molding method for forming a chain of hollow, shaped article bodies of biaxially oriented, normally highly crystalline thermoplastic material from a tube of the material in substantially unoriented condition, but at its orientation temperature, which includes pulling the tube from a first point to a second point, and pushing beyond the second point that portion of the chain formed between the two points; braking the travel of the tube past the first point during at least part of the time it is being pulled, whereby the part of the tube between the points becomes stretched; closing the corresponding mold pieces of a plurality of stationary blow molds on the stretched part of the tube; inflating the portions of the stretched part of the tube within the mold cavities defined by the corresponding mold pieces to form in each the mold cavity one of the bodies, and to biaxially orient the material thereof; and sequentially opening the mold pieces, following the inflating, to minimize snap-back of the chain.
