face 12 34 or 14 34 or in a recess provided there with the thread 13 being guided to this position through a suitable opening at the periphery of the thread reel 12 or 14 respectively referring to fig5 to 10 the following will describe how the thread ends can be reliably secured in kink free manner at the holding pins 28 referring to fig5 a right or circularly cylindrical installation pin 27 is arranged above the holding pin 28 of one of the thread reels 12 or 14 in such a way that its free end face 30 is arranged directly opposite to and confronts the likewise circular end face 31 of the head 28 39 of the holding pin 28 the free end face 30 can contact the end face 31 as seen in fig1 the free end face 30 can also be narrowly spaced from the end face 31 in accordance with the invention the dimensioning of the end faces 30 31 are such that they are congruent to one another at most the end face 30 of the installation pin 27 may be permitted to project slightly beyond that end face 31 of the head 28 39 a hollow cylindrical stripper or scraper 29 is mounted on the outside of the right cylindrical installation pin 28 and can be displaced downward from the basic position illustrated in fig5 in the direction of the arrows onto the installation pin 27 in fig5 a schematically indicated spring 35 biases the stripper 29 in.
