Definitions

  • the present invention relates to combs, and especially to the teeth of combs suitable for combing fibrous webs.
  • each tooth comprises a projecting part and a root portion, with the root portions being fixed integrally to form a unitary base. Then, in a combing operation, the projecting teeth are inserted into a moving fibrous web to order and open the fibres.
  • a comb having a plurality of juxtaposed teeth whose root portions are identical and are connected in a unitary manner, characterised in that the teeth are of at least two different lengths.
  • the ends of the teeth do not lie on a straight line. Therefore, the ends of the teeth act as points on the surface of the fibrous web.
  • the longer or longest teeth are inserted, then any mid-length teeth positioned between the first-mentioned longer teeth are inserted, and finally the shorter or shortest teeth are inserted.
  • the comb teeth are easily inserted into a fibrous web, even one having a high fibre density, thus ensuring satisfactory combing of the fibrous web.
  • Figs. 1 to 3 show embodiments of comb according to the present invention which comprise two kinds of teeth 11 a and 11b which are of different respective lengths.
  • the teeth have identical root portions 12.
  • long teeth 11 a and short teeth 11b are alternately repeatedly juxtaposed, with the root portions 12 fixed integrally to form a fixed base 13.
  • two short teeth 11 b are juxtaposed next to a single long tooth 11 a to form a unit, these units being repeatedly juxtaposed.
  • two short teeth 11 b are juxtaposed next to two long teeth 11 a to form a unit, these units being repeatedly juxtaposed.
  • Figs. 4 and 5 show embodiments of comb according to the present invention which comprise three kinds of teeth 11c, 11d and 11e of respective different lengths. Again, their root portions 12 are identical.
  • a longest tooth 11 c, a mid-length tooth 11 d, a short tooth 11 e and another mid-length tooth 11d are juxtaposed in that order to form one unit. These units are repeatedly juxtaposed with the respective root portions 12 fixed integrally to form a fixed base 13.
  • Fig. 5 a longest tooth 11c, a mid-length tooth 11d, a short tooth 11e, a mid-length tooth 11d, another short tooth 11e and another mid-length tooth 11d are juxtaposed in that order to form one unit, again with these units being repeatedly juxtaposed.
  • teeth used in this invention are not limited just to teeth of two or three different lengths as shown in the aforesaid embodiments. Teeth having a greater variety of lengths can be used, as appropriate to be inserted into a fibrous web effectively to carry out a combing operation.
  • the teeth may be suitably combined to constitute the set of teeth for the comb.
  • the order or arrangement of the teeth is not limited to what is shown in the particular embodiments. Teeth having differing lengths may be juxtaposed at random. The order and arrangement should be such as will best achieve an effective combing of the particular fibrous web being treated.
  • the comb teeth of a comb according to this invention comprise at least two kinds of teeth, of respective different lengths but with identical root portions.
  • the teeth if arranged in an ordered set, have the sets repeated, and the root portions are fixed in a unitary manner. Therefore, the ends of the teeth of the comb do not lie in a straight line as in the prior art combs but lie at different levels. The spaces between the ends of the longest teeth are thus increased.
  • the teeth are inserted into the surface of the fibrous web in a point-like manner, not as a solid edge.
  • the longer or longest teeth are first inserted into the fibrous web, and finally the shorter or shortest teeth are inserted. This means that the teeth can easily be inserted into a web, even into a fibrous web having a high fibre density, thus obtaining an excellent combing effect.
