  • 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.

  • Patent number: 4155136
    Abstract: Intensity of vibrations emitted by tool and workpiece acted upon is reduced by an enveloping mat of floppy fibres. In a heel attacher, for instance, the mat reduces by 14 or more decibels, and an operator incurs no risk of injury to his hands should they be in the path of the mat when it is moved to or from a heel and shoe being attached.
