When joining nonwoven textile fiber webs the fabrics are placed side by side by means of rolls and are commonly transported away. The adjacent webs (7,8) are subjected to a stuffing process (10,36). Thereafter, the stuffed web of larger thickness is slightly stretched by having the successive roll rotate faster than the stuffing roll. In this manner, multiple side by side webs may be joined by fibers near their adjoining edges entangling to interlock and form an integral large-width web.

Method and apparatus for joining nonwoven fiber fabrics, in particular

A carding machine is provided with two doffer units. Each doffer unit comprises a doffer roller and an intermediate roller coordinated thereto, which rollers are shiftable into two different operating positions. In a first operating position, the intermediated roller is out of operation and the doffer roller works in a usual manner in combination with the main cylinder. In the second operating position the doffer roller is out of operational contact with the main cylinder and the intermediate roller, which has the same direction of rotation as the main cylinder, is positioned so as to transfer the fibers from the main cylinder to the doffer roller. The fiber fleeces leaving each of the doffer units may be combined to form a compound fiber fleece. In order to form a thin single layer fiber fleece, one of the intermediate rollers in said second operating position is driven with the speed of rotation such that its circumferential speed is lower than the circumferential speed of the coordinated doffer roller, thus preventing the transfer of fibers from the main cylinder to the doffer roller.

Universal textile machine for optionally manufacturing longitudinally

A system and method for cleaning and feeding textile fibers is disclosed wherein supply units (A) include a cleaning machine (B) fed by a batt forming machine (C) which includes a reserve chute (42) and a formation chute (44). The reserve chute and formation chute are partitioned whereby a serial flow of fiber laden air may be utilized to deliver fibers to a number of the supply units connected in series. Each supply unit (C) may feed a parallel line (10, 12, 14) of card machines (16). Each card machine (16) is fed by a vertical chute feed (18) to which a fiber delivery air flow is delivered from supply units (60, 62, 64). In this manner, a first fiber batt of uniform density across its width is fed to the cleaning machines. The fibers are more uniformly fed and separated to provide more uniform opening and cleaning of the fibers. The individual and cleaned fibers are fed to a vertical chute feed wherein a second fiber batt is formed for feeding to the textile cards.

Textile fiber feeding and cleaning system and method

A carding machine is provided with two doffers. At least one of the doffers has an intermediate roller coordinated thereto. The doffer roller and the coordinated intermediate roller are shiftable into two different operating settings. In a first operating setting the intermediate roller is out of operation and the doffer roller works in a usual manner in combination with the main cylinder. In the other setting the doffer roller is out of operational contact with the main cylinder, and the intermediate roller, which has the same direction of rotation as the main cylinder, is positioned so as to transfer the fibers from the main cylinder to the doffer roller. The second doffer roller may have a second intermediate roller coordinated thereto. The fiber fleeces leaving both doffer rollers are combined to form a compound fiber fleece.

In a carding machine the distance between the doffer roller and the main cylinder can be adjusted to a distance such that the card clothing of the doffer roller is no longer in its operating position with respect to the main cylinder. Further, there is provided an intermediate roller, which, when the doffer roller has been moved away from the main cylinder, is brought into a position such that its card clothing meshes with the card clothing both of the main cylinder and of the doffer roller.
