A carding machine includes a main carding cylinder; a lateral support component situated laterally of the main carding cylinder; and a travelling flats assembly situated above the main carding cylinder and having a working path along an upper circumference. The travelling flats assembly has a first and a second end sprocket positioned at a beginning and at an end, respectively, of the working path; an endless drive element supported by the end sprockets; a slideway having a convex portion following the curvature of the main carding cylinder and a concave portion adjacent the convex portion and following the curvature of the first and second end sprockets, respectively; a fastening device for securing the slideway to the lateral component; and a plurality of flat bars carried by the endless drive element; each flat bar has a flat bar end supported on the slideway.

An automatic startup device in a carding machine includes a roll assembly for discharging the fiber web; and a web transporting arrangement situated under the roll assembly for gathering and advancing the web. The web transporting arrangement is formed of two adjoining, driven endless belts which together define a gap through which the web is discharged downwardly. The two endless belts or portions thereof are simultaneously shiftable horizontally to cause the web discharge gap to assume first and second locations spaced horizontaly from one another. There is further provided a trumpet situated under the web gathering belts. The trumpet has separable parts between which the web is introduced from the web discharge gap. In a separated position the two trumpet parts are at a relatively large distance from one another, whereby the web is discharged by the trumpet in a substantially unaltered state and in a joined position the two trumpet parts are at a relatively small distance from one another, whereby the web is compressed and discharged by the trumpet as a sliver. The trumpet, or parts thereof are moveable horizontally, so that the trumpet inlet is situated substantially vertically underneath the shiftable discharge gap in both of its locations. There are further provided a web delivery arrangement which is underneath the trumpet outlet when the web discharge gap is in its first location and a calender roll pair which is underneath the trumpet outlet when the web discharge gap is in its second location.

An apparatus for transporting at least one can between a sliver furnishing fiber processing machine, e.g. a carding machine, and a sliver fed fiber processing machine, e.g. a drawing frame, by means of a transporting carriage. In order to improve loading and unloading as well as transport of the spinning cans, a loading and unloading device for the can is associated with the transporting carriage, with the loading and unloading device including conveyor elements for moving the can with respect to the transporting carriage.

Apparatus for can changing

An apparatus for removing waste from a card has a circulating perforated component supported spaced from the licker-in in the lower zone thereof; a vacuum generator connected with the inside of the perforated component for drawing air through the perforated component; and a connecting chamber extending from an opening in the lower zone of the licker-in to the perforated component for providing a passage of air and waste drawn by the vacuum.

An accident prevention system for machines having one or more movable components, such as rotatable components, has a cover by means of which access may be had to the movable component and which can be moved to an open position. A latching arrangement normally holds the cover in closed position. An electric circuit is provided including a source of electric energy, a normally open switch and an electrically energizable actuating element which can deactivate the latching arrangement. A detector senses movement of the movable component and, when it determines that the movable component is stationary, completes the electric circuit up to the switch so that when the switch is subsequently operated, the actuating element is actuated and disengages the latching arrangement to permit the cover to be opened.

A fiber processing machine has rotary components, a shroud surrounding the components at least laterally and from above, a suction apparatus including at least one suction head situated in the space surrounded by the shroud for drawing away, by means of an air stream, fiber waste released during operation of the machine. There is provided at least one blower head which is located between the rotary components and the shroud for introducing pressurized air into the space surrounded by the shroud.

A carding wire brush, particularly for revolving flats, with hook-like brush elements which are inserted in a carrying layer and protrude from the carrying layer to form the carding teeth. The tooth face of the carding teeth forms a nearly right or obtuse angle relative to the carrying layer. The tooth flank is chamfered or bent concavely in relation to the carrying layer. The tip region of the carding teeth is nearly parallel to the carrying layer. Polyvinyl chloride may be used as the carrying layer, and tooth flank may be tangent to the carrying layer. The tip region of the carding teeth is at least 10% of the side length of the base wire cross section. The carding wire brush may be used as fixed breakup element underneath the lickerin on the carding machine or above the lickerin on the drum of the carding machine. The carding wire brush may also be used for revolving flats arranged alternately with carding wire brushes having pointed teeth.

A device for withdrawing and gathering a fiber web discharged by a web delivering assembly of a carding machine includes a guide element arranged immediately downstream of the web delivering assembly and has a web guiding face; a support for positioning the guiding face to be movable towards and away from the web delivering assembly; an arrangement for urging the guiding face towards the web delivering assembly into a closed position with a predetermined force; a switch supported adjacent the guiding face for actuation by the guiding face upon movement of the guiding face away from the web delivering assembly in response to a web pressure opposing and exceeding the predetermined force; and an arrangement connected to the switch and responsive to the actuation thereof.

Web guiding device

A device for gathering a running fiber web delivered by a pair of cooperating rolls (forming part of a web delivering assembly arranged downstream of a carding machine) includes at least one operationally substantially stationary guide element having a hollow guiding face. The guide element is supported downstream of and immediately adjacent to the rolls of the web delivering assembly. The hollow guiding face extends transversely to the direction of advance of the web as the latter leaves the rolls and shrouds at least one part of both rolls.

A carding machine has a card cylinder, a doffer cooperating with the card cylinder and a cylinder screen situated underneath the card cylinder and generally conforming to the surface curvature thereof. The cylinder screen has a screen face including a screening portion and a screenless terminal portion. The terminal portion is arranged adjacent the doffer. At least one slot-shaped opening is provided in the screenless terminal portion of the cylinder screen. The opening has a length dimension which is oriented parallel to the width dimension of the cylinder screen.

A vacuuming device for carding equipment for cleaning the revolving flats in which a vacuuming box is located between a licker-in and the adjacent flats deflection roller. The vacuuming box is enclosed on all sides. The region of the flats deflection roller on the inside of the revolving flats, accommodates a guide element for diverting dust-laden air in the direction of at least one intake opening in the vacuuming box. This intake opening is associated with the revolving flats. The guide element may be made hollow to receive dust-laden air, and may be connected in a sealing manner with the revolving flats. The vacuuming box may have two intake openings which are placed so that one of these openings always faces an open gap between the revolving flats. The intake openings may be in the form of slots extending throughout the width of the card. A layer for sealing off the revolving flats, may be made of soft material and may be located on the vacuuming box in front of the intake openings.

An apparatus for detecting metallic bodies in a running textile lap performs the steps of generating a high-frequency electromagnetic field; passing the textile lap through the high-frequency electromagnetic field; and deriving a sensor signal as a function of an alteration of the high-frequency electromagnetic field caused by the presence of a metallic body in the lap.
