Patent ID: 7503100

Claim:
An adjustable machine element assembly for a spinning preparation machine, comprising: a machine element arranged, in use, to lie opposed to and spaced from a roller of the spinning preparation machine and having a working portion and opposed first and second end portions, there being provided a first machine element bearing surface on said first end portion and a second machine element bearing surface on said second end portion; and first and second machine bearing surfaces associated with the spinning preparation machine; wherein said first machine element bearing surface and said first machine bearing surface co-operate to form a first adjusting structure and said second machine element bearing surface and said second machine bearing surface co-operate to form a second adjusting structure, said machine element bearing surfaces and said machine bearing surfaces each being inclined and a direction of inclination of the inclined surfaces of said first adjusting structure being opposed to the direction of inclination of the inclined surfaces of said second adjusting structure, whereby on thermally induced expansion of the machine element in a longitudinal direction relative displacement along the inclined surfaces can take place in such a manner that a spacing of the working portion of the machine element from the roller can be maintained substantially unchanged.
