Machine for cutting material on the biasPUTT EDWARD D.US1580916 * Jun 4, 1921 Apr 13, 1926 Firestone Tire & Rubber Co Machine for cutting material on the bias
This invention relates to machines for cutting material on the bias and has particular reference to a machine in which the tubular material is drawn off a rotatable support over a mandrel in a spiral direction and pulled off of and advanced over the mandrel by a device which simultaneously......

The invention provides a method of working with a travelling head press to cut rows of identical workpieces across wide sheet material. The combination of the press and the means feeding the sheet material through it is so arranged that rows of workpieces can be cut on the bias along transvers...
the increase of pulse energy, more energy accumulates on sheet material so that more energy transmits to the matrix. Hence, HAZ gets thicker. The reduction in HAZ thickness has also been found with the increment of cutting speed and gas pressure as shown inFig. 11(a) and (b), ...

There are some limitations in this study. Firstly, this was a single-center trial involving relatively few patients. Secondly, this trial was single-blind, so the bias caused by the researcher's subjective factors cannot be avoided. Thirdly, it is known that clinical healing (closure of externa...

the cutting edge geometry. Fundamental investigations on material removal as well as on the effects on surface topography, sub-surface properties, and coating adhesion of a subsequently applied PVD coating are performed. To influence the topography and the cutting edge geometry, the preparation timetp...
