Abstract
The combing machine has at least one combing head having combing elements and a carrier for a lap roll for combing. Two pairs of transport rollers and a pair of pressing rollers are provided in the path of the lap from the lap roll to the combing elements. A movable deflector or element is also disposed adjacent the pressing rollers for a lap end. An automatic lap change is carried out when the lap has approximately completely unwound from the roll. The transport roller pairs are used to tear the lap therebetween with the resulting lap end advancing to the pressing rollers which is then stopped. After a fresh lap roll is placed in the machine, the forward end of the lap is moved between the transporting rollers and severed to form a second lap end. The deflector element serves to place the end of the fresh lap onto the previous lap end for combining within the pressure rolls.
