An apparatus for cutting boiler tubes comprising a movable carriage having a cutting means where the carriage and cutting means are supported on a lateral supporting beam secured adjacently to a bank of boiler tubes. The movable carriage means is stabilized with a plurality of bearings means for engaging the lateral beam and preventing strain and vibrations during the cutting process. The cutting means is preferably powered by a pneumatic motor.

Boiler tube cutting apparatus

An apparatus having a sample sectioning device including a cutting mechanism that is operable to cut sections from a sample and a sample holder that is operable to hold the sample. The apparatus further includes a drive system coupled with the sample holder to drive movement of the sample holder and a reciprocating member coupled to the drive system to drive vertical movement of the drive system. The reciprocating member to move in a reciprocating manner within an angle of rotation of less than 180 degrees. A surface orientation sensor may further be provided that is operable to sense an orientation of a surface of the sample held by the sample holder.

Reciprocating microtome drive system

A portable tube cutting apparatus which facilitates smooth even cuts. The apparatus has a frame supporting a movable carriage, a motor driven cutting tool secured to the carriage, and vise-like fasteners for supporting the frame from a stationary object, such as the tube which is to be cut. A pair of spaced parallel rods, secured to the frame, pass through a pair of corresponding cylindrically bored guides attached to the carriage to restrict movement of the carriage to a linear path which passes through the tube which is to be cut while the apparatus is being used. A rack and pinion arrangement operably connected to a lever is preferably provided for smoothly advancing the carriage toward the tube.

a Production method of single-bar-cut V belts includs: a belt tube forming step, a belt tube vulcanization step, and a cutting slitting step. The belt tube forming step includes: forming a tape cartridge having a molded plastic product defibrillators bottom layer; the forming belt tube is formed by vulcanization step for curing the shaped tube with a specially designed tape vulcanizing mold; in the curing process on defibrillators bottom of the molded plastic laminated tape cartridge several integrally formed along one direction and the same transmission intervals spurt strip, and several were located in the spurt strip between the two in which the cutting recess ditch. The cutting slitting step is cutting along the grooves cut into the tube a section of vulcanized belt drive V-shaped belt. The case by the aforementioned steps, it can not generate waste or grinding waste strip, rapid, economical and environmentally friendly to produce a single drive V-shaped belts.

Production method of single-bar-cut V belts

A machine for cutting a profile into the respective ends of a flat rectangular piece of rubberized material having a clamping table with an overhead reciprocating carriage that has a rotating profile cutter that cuts an interlocking profile at a single pass into such material.

Profile cutting machine

A cylindrical expandable sleeve for use in a curing process wherein a pair of annular end portions and a cylindrical expandable body have a longitudinally extending splice with interlocking ribs and surfaces to firmly interconnect such body into a unitary whole for use in successive expansions and contractions.
