摘要:
An apparatus for regulating the surface temperature of a plurality of revolving and substantially identically constructed and arranged heated devices, such as godets or thread rollers in textile machines, wherein a guide or monitor godet is provided in which two means of detecting and transmitting temperature data are used in conjunction with each other as a reference for effectively controlling the surface temperature of all other heated godets in the system.
摘要:
A godet assembly in which a rotated, inductively heated cylindrical godet shell is provided on its inner wall with radially recessed openings from which there extends an axially recessed opening, preferably triangular in a longitudinal section, a non-magnetic material of high electrical conductivity such as copper being advantageously filled into these recessed openings in close adherent contact with the wall surfaces of the openings, such that the openings and preferably with the embedded non-magnetic material are arranged radially and axially to maintain a uniform temperature on the outer circumferential surface of the shell.
摘要:
A device for the transmission of two or more signals, such as control signals, between a rotatable member such as a roller and a fixed or stationary member, e.g. as required in textile machines for the control of heated godets or rollers which convey thread on a heated surface maintained at a predetermined temperature, said device including at least two elongated arcuate signal transmitting elements carried rotatably on an annular planar support secured to the godet or roller and preferably two stationary transmitting elements for each of the rotatably carried transmitting elements wherein at least one of the stationary transmitting elements always remains in an operative coupling position with a rotatably carried transmitting element to form an individual transmitting unit for one of the signals.
