Abstract
Abstract Drafts of preselected weight are sliced into a preselected number of slices by passing the material to be sliced through a curtain of radiation to measure the density of the material, and this measurement is used to calculate the length of each draft, which measurement is stored and subsequently read out to control the operation of a stepping hydroelectric motor which pushes the material through a cutting station at the proper speed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
58 words
A method of slicing a plurality of drafts of a resilient material by moving said material through a slicing station comprising the steps of exerting a compressive force on said material to move said material through said station, relieving said force after each of said drafts have been sliced to prevent the slicing of slivers between said drafts.
Claim 2
Independent Claim
58 words
A method of slicing a plurality of drafts of a resilient material by moving said material through a slicing station comprising the steps of exerting a compressive force on said material to move said material through said station, relieving said force after each of said drafts have been sliced to prevent the slicing of slivers between said drafts.
Claim 3
Dependent Claim
27 words
A method as set forth in claim 1, in which said force is relieved by reversing the direction in which said material is moved through said station
Claim 4
Dependent Claim
38 words
A method as set forth in claim 1, in which said material is moved through said station by a ram driven by a motor and in which said force is relieved by reversing the direction of said motor.
Claim 5
Dependent Claim
45 words
A method as set forth in claim 3, in which said motor is a stepping motor and said force is relieved by driving said motor at least one step in a direction opposite the direction it was driven to move said material through said station.
