Abstract
A method for fastening a clothing strip to a card-flat bar by a fastening means in the form of clips is presented. In this case, the clips are integrally formed onto the card-flat foot by press rams guided simultaneously from both sides of the card-flat bar and parallel to the plane of the clothing strip. The clip is integrally formed onto the card-flat foot and loops around the latter with a looping angle of less than 90° and more than 30°. A corresponding tool for carrying out the method and also a revolving card flat are likewise proposed.
Claims12
A revolving card flat comprising:
- a card-flat bar having a card-flat foot, a web lying above the card-flat foot, a flexible clothing in the form of a clothing strip, and at least one fastening element in the form of a clip;
- the clip attached by a first portion to the clothing strip;
- the clip having a second portion that extends along one longitudinal side of the card-flat bar;
- the clip having a third portion that partially loops around the card-flat foot with a looping angle that is less than 90° and greater than 30°.
A method for fastening a flexible clothing in the form of a clothing strip to a card-flat bar of a revolving card flat with two clips, the card-flat bar having a card-fiat foot and a web lying above the card-flat foot, the method comprising:
- fastening a first portion of the clips to mutually opposite longitudinal sides of the clothing strip;
- forming a second portion of the clips to extend along the longitudinal sides of the card-flat bar;
- forming a third portion of the clips against the card-flat foot with oppositely oriented press rams that move simultaneously and transversally relative to the longitudinal direction of the card-flat bar, the press rams guided simultaneously from both sides so as to move parallel to the plane of the clothing strip.
A tool for fastening a flexible clothing in the form of a clothing strip to a card-flat bar of a revolving card flat with two clips, the card-flat bar having a card-flat foot and a web lying above the card-flat foot, the clips having a first portion fastened to mutually opposite longitudinal sides of the clothing strip and a second portion that extends along the longitudinal sides of the card-flat bar, the tool comprising:
- a receptacle for receipt of the card-flat bar with a third portion of the clips extending above and generally parallel to the longitudinal sides of the card-flat bar;
- and
- opposite press rams configured for simultaneous transverse movement relative to the longitudinal orientation of the card-flat bar within the receptacle so as to engage and press the third portion of the respective clips inwards against a bearing face of the card-flat foot.
