US 3,942,302 A · End closing machine for roll wrapped packages

Abstract

An end gathering machine for gathering the loose ends of flexible wrapping material at the end of roll wrapped articles, the machine being located between an infeed conveyor and a discharge conveyor which are used to intermittently transport the roll wrapped articles in a timed sequence to the end gathering machine, the articles being initially aligned with the lead end positioned in the machine and subsequently aligned with the trailing end positioned within the machine. The machine includes first and second sets of upper and lower slides which are movable simultaneously toward and away from each other to gather the loose material at the axis of the rolled article and including automatically sequenced clip assemblies for binding the gathered material to seal the article, the slides being adjustable to gather the material at the axis of the article, the system being electrically interconnected to automatically sequence the movement of the wrapped articles from a storage position through the end closing machine to a loading conveyor.

4 more elements

An end closing machine for gathering the ends of a wrapping at each end of a rolled article, said machine comprising:

a frame,
an upper and a lower slide supported in a spaced relation on said frame for movement toward and away from each other, said upper slide including a number of plates mounted in a parallel spaced relation and each plate having an inverted V-shaped notch, said lower slide including a number of plates mounted in a parallel spaced relation and each plate including a V-shaped notch corresponding to the inverted V-shaped notch of the plates on said upper slide,
two of said plates on said upper slide being arranged to cooperate with a single plate on the lower slide for gathering loose material at the end of the prewrapped roll at the axis of the roll,
two pairs of stabilizing sprockets mounted on said frame,
one of said pair being located above the upper slide and the other pair being located below the lower slide,
a chain beam,
a first pair of chains having one end connected to the lower slide and wrapped around the upper pair of equalizer sprockets, the other end of the chain being connected to the chain beam,
a second pair of chains having one end connected to the lower slide wrapped around the lower equalizer sprockets and the other end connected to the chain beam,
means for connecting the said upper slide to said chain beam,
a pneumatic piston and cylinder assembly having one end connected to the frame and the other end connected to said lower slide whereby on movement of said lower slide said upper slide will move an equal distance in the opposite direction,
and means mounted on said lwoer slide for binding the gathered ends of loose material to seal the package.
