Abstract: Apparatus for and a method of handling flexible tubes, for example in the production of a liner for a cargo container to provide a tubular attachment on the liner. A tube 16 in the form of a web of flexible material is drawn over a support 39 mounted on a carrier 29,30, the support having a greater area than that of the opened-out tube and being tilted to the radial plane (FIG. 2) during the drawing action. The support is then moved to the radial plane (FIG. 4) so as to stretch the tube 16 in the region of the support whereafter the tube is cut from the web, in the vicinity of the support. The support 39 is moved to a further processing station (FIG. 8), carrying the cut off tube 16, whereat the tube is released from the support 39 by tilting the support once more and withdrawing the support from the tube. The support is then returned to its initial position ready for another cycle of operation.

Abstract: The invention relates to a cutting mold set of metal tubes, comprising of the following: a cutting mold unit that moves in relation to a lower mold unit is installed on one side of an upper mold unit, the upper mold unit is capable of moving in relation to a lower mold unit. On the cutting mold unit is installed a first mold block with a cutting hole, and on the lower mold unit is installed a second mold block with a through hole, the cutting hole and the through hole matching and communicating with each other. With the metal tube inserted inside the through hole and the cutting hole, when the upper mold unit and the cutting mold move toward the lower mold unit, the cutting hole and the through hole move in relation to each other to create a cutting force to cut the metal tube, thereby achieving the objectives of speedy and safe operation, enhancing safety in cutting operation, and reducing waste iron scraps.

Abstract: A punch and die device for working such as punching of a pipe material is disclosed, of which internal die means can easily be inserted into a pipe material even if an open end of the pipe material to be worked has burrs inward extending therefrom, and in which it is easily detected whether the internal die means is pushed toward a lateral side or lateral sides of the pipe material and thereby firmly held. The punch and die device for working a pipe material comprises: external punch means located outside a pipe material P, and internal die means K inserted in the pipe material for cooperation with a punch 30 of the external punch means to work the pipe material P; the internal die means K being divided into two parts in a direction orthogonal to that of reciprocating motion of the punch 30 of the external punch means, one 1 of the parts having working function and the other 2 having no working function, the non-working part 2 being forward and backward movable in the opening direction, i. e.

Abstract: A device for punching holes in a bicycle rim includes a flange extending radially from a base, the flange having a plurality of rails disposed thereon each for a puncher slidably disposed thereon. Each of the punchers has a first block and a second block respectively extending upwardly from two ends thereof and a cylinder disposed longitudinally to each of the first blocks having a shaft retractably extending therefrom which extends through the first block and has a pin member disposed on a free end thereof. Each of the second blocks has a longitudinal hole defined therethrough so that when a bicycle rim is disposed between the first blocks and the second blocks each of the pin members punches a hole through the rim.

Abstract: Method for severing the ends of tubing by feeding the end of a tube through a die such that its end to be sheared extends beyond the die while presenting a shear blade with a pointed end in the interior of the tube end. After the shear blade is inserted into the tube, relative vertical movement between the shear blade and the tube is effected to cause the pointed end to initially puncture the tube wall adjacent the die. The shearing blade is thereafter shifted laterally and vertically to shear remaining portions of the tube wall.

Abstract: A tooling assembly for use with a mechanical impact press includes a pair of die blocks which effect cutting of rods, bars and tubes by the rapid misalignment of aligned apertured tools. Realignment is achieved by a reciprocable cam which also limits the extent of misalignment. Means are provided for clamping or dragging the end of a workpiece stock upstream from the prospective cutting plane. A wedge shaped recess adjacent to the aperture of the movable tool or die block provides a high degree of uniformity in workpiece length as measured at various points of a given workpiece. Where the workpiece stock is tubular, a floating mandrel is disposed within the workpiece in the upstream tool or die block while a reciprocable mandrel supports, receives, resizes and discharges the tubular workpiece.

Abstract: An apparatus to simultaneously punch a series of louver holes in a tubular workpiece. The apparatus having a series of punches angularly spaced around the workpiece, which punches are caused to reciprocate by the engagement thereof by a series of inclined surfaces of a rotatable member located around the workpiece. The apparatus further includes gripping means to hold the workpiece during punching operations and to move the workpiece in between successive punching operations.

Abstract: A preferred embodiment of the invention provides tube cutting apparatus including, a head structure mounting cutter means defining a cutting station for a length of tubular material, an elongate rod-like structure for mounting the tubular material, tube engaging means for advancement of said tubular material along said rod-like structure to said cutting station, support means for said rod-like structure including a portion of table-like form, means for an initially free pivotal connection of said table-like support portion to said head structure and a pedestal type support for the opposite end of said table-like support portion including means for a lateral adjustment thereof about said pivot means to effect a precise alignment of said rod-like structure with said cutting station.
