Nail brush crimper

A method of sizing a crimper adapted for crimping brushes that are of different sizes, the brushes being adapted for applying a coating to a human nail, the method comprising the steps of:

• adjusting an allowable range of motion of a crimper comprising:
• a pair of guide shafts, each guide shaft having an upper end portion and a lower end portion;
• an upper jaw coupled to the pair of guide shafts adjacent the upper end portion of the guide shafts, the upper jaw comprising an upper plate and an upper jaw body coupled to the upper plate;
• a lower jaw moveably coupled to the pair of guide shafts, the lower jaw comprising a lower plate and a lower jaw body coupled to the lower plate, the upper jaw and lower jaw being moveable relative to each other within the allowable range of motion;
• an adjustment plate coupled to the lower end portions of the pair of guide shafts such that the lower jaw is located between the upper jaw and the adjustment plate;
• and
• an actuating cam configured to interface with the lower plate and the adjustment plate and being rotatable relative to the lower plate and the adjustment plate to facilitate movement of the lower plate relative to the upper plate;
• the adjustment of the allowable range of motion including movement of the adjustment plate relative to the upper jaw.

A crimper for crimping brushes used in applying nail care products to human nails, the crimper comprising:

• an upper jaw and a lower jaw moveable relative to each other between a separated position and a crimping position, the distance between the upper jaw and lower jaw decreasing as the upper jaw and lower jaw transition from the separated position toward the crimping position, the upper jaw and the lower jaw being configured to crimp a brush when transitioned toward the crimping position;
• an adjustment plate positioned relative to the upper jaw and lower jaw such that the lower jaw is located between the upper jaw and the adjustment plate;
• and
• an actuating cam configured to interface with the lower plate and the adjustment plate, the actuating cam being rotatable between a neutral position and an actuated position, the upper jaw and lower jaw transitioning from the separated position toward the crimping position as the actuating cam rotates from the neutral position toward the actuated position.
