Abstract: A track system for launching and retrieving a boat carried on a trailer having two laterally spaced back wheels and having a front wheel which is centered laterally with respect to the back wheels. The system includes two laterally spaced tracks for guiding the back wheels of the trailer and further includes a laterally centered and forwardly projecting track for guiding the front wheel of the trailer. The tracks are adapted to be laid on a bank to establish a smooth and compliant surface enabling the trailer to be backed quickly and easily down the bank and into the water for purposes of launching the boat and also to enable the trailer to be easily pulled up the bank during retrieval of the boat. The tracks are tied together by and are adjustable laterally along longitudinally spaced bars. Also, the tracks are made in sections adapted to be coupled together to form a track system of desired length.

Abstract: A cutter employing two heated eccentrically mounted rollers adapted to coact with each other in order to sever a material by means of a crushing action is utilized in conjunction with a transport member to cut predetermined lengths of material from a continuous roll of said material. The cutting action of the heated rollers provides cut ends of the material which may be readily spliced together without the use of gum strips.
