Elementary treatise on the finishing of white, dyed, and printed cotton goods . arge or small cloth rollers in iron or woodare employed, according to the finish to beobtained.

It is essential to roll the goods very tightlyand evenly, also to put on the roller before bat-ching, a strong material or lapping and coverthe fabric when rolled up with lapping. Although the chest mangle gives superiorresults, it has serious drawbacks; it occupies muchspace, requires great motive power, often needsrepairing on account of the shocks, occasioned bythe backward and forward motion of the chest, 256 FINISHING IN GENERAL. and lastly its construction and fitting up are veryexpensive. Efforts have been made to replace it by arotary mangle, this requiring less space andvery little repairs, being constructed entirely ofmetal; the movement is regular and the workingof it much easier than the chest mangle. Lastlywith the rotary mangle the speed and pressure. Fig. 101. Horizontal hydraulic mangle. can be regulated which cannot be done with the ordinary one. We will commence with the hydraulic mangle. The first hydraulic mangle was invented by Kaselowski (Prussian patent of 1850) fig. 101, page 256. It consists of an ordinary hydraulic press Z,provided with a plate e, and a table c, between MACHINES EMPLOYED IN FINISHING. 257 which works a horizontal press-plate d, movedto and fro by the piston-rod f, of a horizontalsteam engine; between the plate d, and the twotables c and e the rolls of cloth a and b to bemangled are placed. The piston of the hydraulicpress acts on two cog-geared arms h h, moveableat their axis g, and arranged to accommodatevarying diameters of mangling rolls.
