Abstract
A method and apparatus for securing card-clothed tops to the flats of revolving flat-type carding machines is disclosed, which obviates the necessity for specialist machines used for securing clipped tops to the flanges of the flats. A special type of top clip is provided which, besides being preformed to engage with the bottom side of the top as is usual, also has an inward hooked formation along its upper longitudinal edge. In addition, various kinds of tensioning elements are provided, each of which is engagable with the hooked formations on the clips, and is resiliently loaded, so that in the assembled condition, it causes the clips to pull the top tightly into engagement with the flanges of the flat.
Claims12
A method of securing a card clothing top to a carding machine flat, said flat having flanges comprising the steps of:
- engaging a clip with both said top and said flat flanges, said clip having a first preformed inward formation engageable with the card clothing top and a second preformed inward formation engageable with a resilient tensioning device between said second inward formation on said clip and the flat flanges, wherein said tensioning device exerts a force in a direction to press said first inward formation towards a main surface of said flat flanges, whereby the preforming of said second inward formation ensures that said top is secured to said flat without bending said clip to produce said second formation after said top has been offered up to said flat.
A clip for securing a card-clothing top to a carding machine flat, comprising:
- a median spine portion;
- a fist inward formation from said median portion adapted for engagement with the card-clothed face of the top and a preformed second inward formation from said median portion adapted for location over a flange of said flat and further adapted for engagement with a tensioning device, wherein said clip requires no bending to produce the second inward inturned formation after application of said clip to said top and to said flat.
In a carding machine, a flat having a flange and a main surface formed on said flange, a card-clothed top for application to said main surface of the flat flanges and clips for securing said top to said flanges, wherein each clip engages with a top and has a preformed inward formation, tensioning means engages between said flat and said preformed inward formation to apply a force to said clip through said inward formation, in a direction to cause said clip to pull said top towards the flat flanges.
