    • Disclosed is a paper feeding device (10) comprising a storage surface (14) for a stack of papers (12), with a leading edge (14a), a trailing edge (14b), and a first and a second side edge (14c, 14d). The surface (14) is adapted to be moved vertically. The device further comprises a vacuum feeder (16) for feeding papers from their position on the storage surface (14) and imparting on an uppermost sheet of paper (12a) a horizontal displacement, and a blower arrangement (18, 20) adapted to provide a curtain of air separating the uppermost sheet of paper (12a) from the rest of the stack of papers. The device further comprises a sensor arrangement (22) arranged to determine where the upper paper sheets in the stack of papers (12) start to separate from the rest of the paper sheets, the sensor arrangement (22) comprising a plurality of infrared reflective sensors (22a).

    • An optoelectronic yarn sensor assembly (S) for a yarn feeder (F), the assembly comprising a housing (H) with optical axes defining light channels (LC), a positioning socket (3) for a receiving/emitter component (D), (R) and a holding structure (4) for an optical lens (L), at least the inner light channel walls consisting of plastic or metallic material. An inwardly protruding annular light barrier (B1, B2) and/or outwardly recessed annular light trap (T) is provided in each light channel (LC) adjacent to the positioning socket (3) and adjacent to the holding structure (4). A channel section (5) of the light channel extends between opposite annular light barriers and/or light traps. The inner diameter of the channel section (5) is larger than the inner diameter of the respective annular light barrier and/or light trap.
