Apparatus for dispensing measured lengths of tubular films onto an armature

摘要

An apparatus for dispensing measured lengths of a sleeve material upon an armature, especially adapted for dispensing a plastic cover upon a toilet seat, includes a source of sleeve material fed onto the armature and collected upon a take-up reel. The cover is provided with a uniform series of marks along its length which are sensed and counted to control the operation of a motor drive which directs the sleeve material to and from the armature. Timer circuits are employed to cause motor cut-off if the required length of sleeve is not dispensed within a given length of time and to inhibit motor start for a fixed period after a dispensation. The sleeve-accepting end of the armature may include an angular horn to permit the sleeve to smoothly pass onto the seat.
