Abstract
An endless elastic band is severed from a tube of resilient material while the interior of the resultant band is being engaged by tensioning fingers which can be manipulated to deliver the band in at least partially expanded condition.

Apparatus for use in the manufacture of resilient bands comprising means for displacing a tube of resilient material longitudinally towards a cutting station, a band engaging station downstream of said cutting station and comprising at least two spaced fingers for entering the leading end portion of the tube on the egress side of the cutting station, cutting means at the cutting station and movable transversely of the tube to sever the leading end portion of the tube from the remainder of the tube to form a band, means for urging the fingers of the finger arrangement apart to tension the severed band against said fingers, and means for displacing the spread fingers bodily to remove the severed band from said cutting station to clear said cutting station for the next cycle.
Apparatus for use in the manufacture of resilient bands comprising means for repetitively severing from a length of tubular material transverse sections thereof which are short compared to the material length to form endless bands of said material and means adjacent said one end for mechanically engaging said successive short transverse sections one by one before severance thereof from said tubular length and independently of the remainder of said tubular length to permit removal of such sections after severance thereof.
A method of manufacturing endless elastic bands which comprises the steps of advancing a length of tubular elastic material through a severing stage to sever from one end of said length successive transverse sections thereof which are short compared to the material length to form endless bands, and before each said short section is severed from the remainder of the length, mechanically engaging each such short transverse section individually one by one and independently of the remainder of the the material length to permit each severed section to be removed from said severing stage.
