Abstract
In order to avoid a damaging of the guiding table and of the bottom apron guided around it when a lap formation occurs on the bottom delivery roller of a drafting unit, it is known to arrange the table top of the guiding table so that it can be swivelled away. In this known construction, a leaf spring is provided which holds the table top in its swivel position. In order to ensure a secure and precise guiding during the swivel movement of the table top, the new apron table is constructed with a projection which is provided on both sides with opposite surfaces which are positively guided during a swivel movement of the table top in a receiving device developed as a connecting link guide.
