  • Heel attaching machine
    Patent number: 4491263
    Abstract: A heel attaching machine is provided with an abutment mounted on a pneumatic piston and cylinder unit. After a shoe upper and heel have been positioned on the nailing stand of the machine, the abutment is moved upwards into engagement with the shank region of the insole of the shoe. The abutment then serves to prevent the upper from tipping about the edge of the nailing stand during insertion of the heel attaching nails.
