Abstract: An automatic necktie neckband tacker, comprising a guage having inner peripheral edges defining an opening substantially equal to the size of a neckband for securing a neckband therein, an upper clamp forming a clamp opening therein substantially equal to the opening of the gauge and aligned therewith, the upper clamp moveably disposed above the guage constituting a clamping unit therewith for clamping therebetween a tie at a neck area thereof adjacent the neckband, and a clamp and cutting blade carrier for clamping and cutting, respectively, an upper needle thread. The upper clamp has a formation for guideably mounting the clamp and cutting blade carrier for movement of the latter upon actuation thereof into a withdrawn position under the upper clamp, as well as into an operative position projecting into the clamp opening. A pneumatic cylinder is operatively mounted on said upper clamp moveably jointly therewith, for actuating the clamp and cutting blade carrier.
