    摘要: The invention provides a process for preparing an aqueous polymer dispersion of a copolymer CP of at least two different monomers M1 and M2 by free-radical aqueous emulsion polymerization of the monomers M in the presence of at least one initiator, at least 80% of the monomers M and at least 75% of the initiator being supplied continuously to the polymerization reaction during its course, which comprises changing the rate at which the initiator is supplied to the polymerization reaction a number of times, or continuously, during the polymerization reaction. The invention further provides the polymer dispersions obtainable by this process, polymer powders prepared therefrom, and for the use of the dispersions and/or of the polymer powders to prepare pressure sensitive adhesives.

    摘要: A latch needle includes a head; a cheek having two facing side walls each having an inner wall face and an outer wall face; a sawslot defined by the inner wall faces of the side walls; and a pivot pin being formed at least on one of the side walls by plastically deforming the side wall. The pivot pin extends from the inner wall face of the side wall into the sawslot. The latch needle further has a first depression provided in the outer wall face of the side wall in alignment with the pivot pin. The first depression includes a bottom having a peripheral region in which a second depression is provided. A needle latch cooperates with the head and has a latch shank accommodated in the sawslot. The latch shank has a hole into which the pivot pin extends for forming a bearing support for the needle latch.

    摘要: A tool for a stitch forming machine which includes a bed and a plurality of guide grooves disposed in the bed, the tool including a shank slidably disposed in one of the guide grooves. The shank includes an end having a stitch forming device, and has a butt and at least two bends spaced from one another along a longitudinal direction of the shank. The bends are oriented toward the same side of the shank and are disposed in a region of the shank which, during sliding movement of the shank during operation of the knitting machine, remains within the guide groove.
