Shabbat Scenarios: Fit To Be Tied - More Applications of the Melacha of Koshair #3

Can you tie a knot on a Torah belt (gelilah) on Shabbat?

Today most shuls have clips or pre-tied belts, but the question may still come up. On Shabbat morning the knot is by definition temporary, as the Torah will be taken out again later in the day during Mincha. However, after Mincha the Torah will not be read again until Monday morning, thirty six hours later. According to the Rambam and the Rif it is still considered an ordinary temporary knot and it is permitted. According to Rashi, it is a quasi-permanent knot. There is a machloket if a quasi-permanent knot is a knot that is meant to last for more than a day or more than seven days. Therefore, the Mishna Berura advises against tying a knot meant to stay more than a day. However, in cases of need, there is room for leniency.

The Shulchan Aruch writes, based on the Rambam and the Rif, that tying a temporary knot for a mitzva is permitted. However, if the Torah will not be used again for more than six months, one should not tie such a knot on Shabbat.

 

Adjusting a necktie

Making a Half Windsor slip knot in a tie is permitted.  A Double Windsor knot could pose a problem as it is considered a more professional type of knot. There may be room for leniency based on a comment of Sharei Teshuva that discusses belts. A double knot on a raincoat belt is permitted because it is a loose, ordinary, temporary knot that is undone regularly. Both a belt and a tie are made of thick material which is usually tied loosely. However, tying a tight double knot on a women’s thin dress belt should be avoided.

Is it permitted to make a tight double knot on Shabbat with the intent to untie it that day?

Can you tie tzizit knots on Shabbat with the intent to untie it immediately after Shabbat?      According to the Pri Megadim, it is permitted as the knot is temporary. However, the Mishna Berura disagrees. Normally, people do not undo tzizit or tefillin knots.  If the nature of the knot is permanent, then an individual’s intent cannot nullify the intent of the masses. Therefore, such permanent kinds of knots should not be made on Shabbat even if they will be untied that day.

Twist-ties

The Rambam writes that twisting twine together to make a thick rope is a derivative (tolda) of Koshair and is Biblically prohibited. Are twist-ties analogous to this? Rav Auerbach and Rav Elyashiv rule that it is prohibited, certainly if one does not intend to untie it. Other poskim disagree and permit it. In general one should avoid using twist-ties on Shabbat. However twisting the tie once is permitted.
