Abstract
A cooling system and method for a carding machine having covering elements covering the swift of the card and a revolving flats arrangement defining the main carding zone. Heat is removed from the covering elements and/or the revolving flats arrangement by passing a heat-receiving medium, such as a liquid or gas, through ducts formed in covering element segments and/or between adjacent flats of the revolving flats arrangement.
Claims22
A card comprising:
- (a) a swift for conveying material in the card;
- (b) means at least partially circumferentially surrounding said swift and arranged in spaced relation with respect to said swift;
- and
- (c) means for removing heat from said circumferentially surrounding means.
A card comprising:
- (a) a swift for conveying material in the card, said swift including covering means;
- (b) means defining a main carding zone;
- (c) means for removing heat from at least one of said covering means and said means for defining a main carding zone;
- (d) said means for defining a main carding zone comprises an arrangement of revolving flats;
- and
- (e) said means for removing heat comprises at least one duct between adjacent flats of said arrangement of revolving flats, and heat receiving medium flowing in said at least one duct.
A carding method for a card, said card comprising a swift, means at least partially circumferentially surrounding said swift and arranged in spaced relation from said swift, said carding method comprising the step of removing heat from said circumferentially surrounding means.
A carding method for a card, said card comprising a swift, means covering said swift and means defining a main carding zone, said carding method comprising the steps of removing heat from at least one of said covering means and said means for defining a main carding zone, revolving an arrangement of flats in said main carding zone, and passing a heat-receiving medium between at least two of said flats to remove heat from said means defining a main carding zone.
