Why are there revolving signs at the entrance of barber shops? How is this rotating sign made?

Firstly, the origins of the barbershop spin-off can be traced back to the time of haircuts, when surgeons also performed tooth extractions and bloodletting operations. This red and white stripe represents blood stained and clean bandages tangled in the wind. As time passed, barber shops no longer performed this procedure, but this symbol of history remained. The manufacture of this traditional rotating column lamp.

Second, first put the stripes on the wooden cylinder. The wooden cylinder used depends on the size of the signboard. Use a blade to carve notches on both ends of the lining. The lining is made of paper and vinyl. Made of resin, it has been treated with the exterior of the house to avoid fading. According to the notches on it, the workers cut off the excess part to reach the appropriate length. Then use rivets to fix the trademark on the bracket, and then use bolts to fix it on the upper and lower supporting castings. The frame and castings are made of aluminum to prevent rust.

Third, after confirming that the casting has no errors, it is necessary to install the glass cylinder. The glass cylinder can be made by extrusion or blowing. Finally, the cylinder is tightened, and then a special filling is prepared. Mix the caulking powder evenly and apply it to the gap between the aluminum column key and the glass cylinder. The caulking fluid will dry out after five minutes. Then remove the excess compound at both ends of the cylinder, leaving a flat and tight surface, and then spray it with green. Clean the inside and outside of the glass with detergent. The workers put the assembled parts on the hooks, apply caulking, and then apply a layer of colored sealant to prevent water from entering inside.

Fourth, the worker then puts in the motor device, which will rotate the printed lining in the glass cylinder. After installing the motor, install the printed lining on it, and then install two brackets. Lamp, then fix all the parts in place, install a rust-proof aluminum casing, and install a second light bulb to illuminate the white glass ball at the top. Finally, the workers connected the sign to the power source and confirmed that the motor, two light bulbs and lining were all functioning properly, and the rotating lamp post was now complete.
