As quoted from:
Shulchan HaMelech, a Kitzur Shulchan Aruch in 3 volumes as compiled by Maharan HaRav Shmuel Laniado z'al, 1923 with the supplement "Al HaShulchan" containing various opinions compiled by Ezra Basri, Chief Justice of the District Court, Jerusalem in 1992.
We would also like to dedicate this learning for the speedy and complete recovery of our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia. Please have him in mind when studying.

6. If a person removed his tallit, even if he had the intention of putting it on again immediately, he must recite a new blessing when he puts it on again. (Shulchan Aruch 8) Others are of the opinion that he should not recite a new blessing when he had intention to put it on again (this opinion is followed by all later authorities). Similarly if his tallit fell off unintentionally and he puts it on again he does not recite a new blessing. (Later Authorities)
