Embodiment Construction

[0030] figure 1 is a schematic view of a first embodiment of a lap guiding device. This view shows a lap roll 2 resting on a front lap roll 4 and a rear lap roll (not shown). The lap 3 is brought to the lap splicing device 6 by rotating the lap drum 2 . The lap splicing device 6 is used to splice the starting point of the lap 3 of the new lap drum 2 to the end of the lap on the empty lap drum. For a better understanding of these processes, the lap splicing device is only schematically shown here. During the splicing process, lap splicing is performed by the lap splicing device 6, placing the start of the new lap 3 from the new lap drum 2 to the end of the old lap web. The overlapping creates a thick spot which is then pressed by means of a transport roller 7 connected to a pressure roller 8 onto which it can be lowered. After the transport roller 7 the lap 3 reaches the upper lap inlet 10 . In the upper roll inlet 10 , the lap 3 is guided between the upper cover 11 and th...

Abstract

The invention relates to a lap guiding device for a combing machine for guiding a lap (3). The lap guiding device comprises a side frame (18), a cover (24), a pressure roller (8), a lower lap inlet (14) and an upper lap inlet (10). The lower lap inlet (14) comprises a lower cover (15) and a lower lap guide (16), which is at a distance from the lower cover (15) in the region of the lap (3) to be guided, and the upper lap inlet (10) comprises an upper cover (11) and an upper lap guide (12), which is at a distance from the upper cover (11) in the region of the lap (3) to be guided, the upper lap guide (12) is connected to the lower lap guide (16) by a flexible element (17). The upper cover (11) is fastened in the lap guide independently of the upper lap guide (12) by means of a retaining device provided for fastening the upper cover (11) in the side frame (18) or to the cover hood (24) or to the pressure roller (8).

Description

technical field [0001] The invention relates to a lap guiding device for a combing machine for guiding a lap, the lap guiding device comprising a side frame and a cover as well as a pressure roller and a lower lap inlet and The entrance of the upper cotton roll. Background technique [0002] In a combing machine comprising an automatic lap piecing device, as known from EP 0 368 059 A1, the starting point of a lap web (lap web) from a new lap is automatically spliced ​​to a lap web from a previous lap. The end point of the lap fiber web, thus ensuring the predetermined overlap (overlap) of consistent quality of the two lap ends. [0003] After using a lap splicing device to join the two ends of each lap web, the laps are fed in the direction of transport by means of transport rollers via a lap guiding device such as that known from CN206467357 U to the feed drum of the comber. A common lap guide has an upper lap inlet with an upper cover and an upper lap guide connected to...
