2. Bead roller - Wikipedia

   en.wikipedia.org/wiki/Bead_roller

   A Bead roller is a machine tool that makes rigid lines in sheet metal to make surfaces more rugged and durable. The lines bead rollers add to sheet metal prevent warping and disfigurement by adding structural integrity to the metal.

3. Plate rolling machine - Wikipedia

   en.wikipedia.org/wiki/Plate_rolling_machine

   There are different kinds of technology to roll the metal plate: Four-roller machines have a top roll, the pinching roll, and two side rolls. The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate.

   A 1923 electric Miele washing machine with a built-in mangle The Oxford English Dictionary dates the first use of the word mangle in English from 1598, quoting John Florio who, in his 1598 dictionary, A World of Words , described "a kind of press to press buckram , fustian , or dyed linen cloth, to make it have a luster or gloss".

5. Rolling (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Rolling_(metalworking)

   For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.

6. Roll bender - Wikipedia

   en.wikipedia.org/wiki/Roll_bender

   A roll bender is a mechanical jig having three rollers used to bend a metal bar into a circular arc. The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing. Two outer rollers, usually immobile, cradle the bottom of the material while the inner roller, whose position is adjustable, presses on the ...

7. Embossing (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Embossing_(manufacturing)

   Sheet metal embossing is a metalworking process for producing raised or sunken designs or relief in sheet metal.In contrast to coining (which uses unmatched dies), embossing uses matched male and female dies [1] to achieve the pattern, either by stamping, or by passing a sheet or strip of metal between patterned rollers. [2]

8. Shear forming - Wikipedia

   en.wikipedia.org/wiki/Shear_forming

   1. A sheet metal blank is placed between the mandrel and the chuck of the spinning machine. The mandrel has the interior shape of the desired final component. 2. A roller makes the sheet metal wrap the mandrel so that it takes its shape. As can be seen, s1 which is the initial wall thickness of the workpiece is reduced to s0.

9. English wheel - Wikipedia

   en.wikipedia.org/wiki/English_wheel

   Planishing manually using dollies and slapper files or planishing hammer, after hammer forming is very labour-intensive. Using a pear shaped mallet and sandbag to stretch the sheet metal , or by raising on a stake, speeds up the fabrication of higher crown sections. (A stake is a dolly, that can be much larger than hand held dollys, typically ...
