Abstract An automatic border panel measuring and cutting machine wherein motorized pinch rollers feed a measured length of a mattress border panel and then stop while a pivotally mounted knife swings from a ready position through a cutting zone, in which it cuts off that measured length, and then returns to its ready position to start the next feed and cut cycle. The knife, which is pivotally mounted at one end, has its opposite or free end not only connected to an air cylinder piston, which moves the knife back and forth for cutting and return purposes, but also engaged, during the cutting movement, by a yieldable guide means which directs the cutting edge of the knife into progressively tighter yieldable cutting (and knife-sharpening) engagement with a fixed cooperative cutting edge on the machine. The air cylinder is mounted for right and left and for front and rear pivotal movements to accommodate the corresponding movements of the blade.
A border panel measuring and cutting machine, comprising: A. means providing a fixed cutting edge; B. motorized panel-feed means operative, when actuated, to feed a border panel forwardly over said cutting edge; C. a knife blade pivotally mounted at one end for movement back and forth across said cutting edge between ready and spent positions; D. power means operative, when actuated one way and the other, to move said knife from its ready position to its spent position to cut said panel and vice versa to return said knife to its ready position; E. control means for automatically actuating said power means; and F. yieldable means engaging the knife during its panel cutting movement and, through such engagement, pressing the cutting edge of the knife yieldably into cutting engagement with a panel on said fixed cutting edge, 1. said yieldable means includes a bar pivotally mounted at one end and yieldably urged at its opposite end into engagement with the knife.

A border panel measuring and cutting machine, comprising: A. means providing a fixed cutting edge; B. motorized panel-feed means operative, when actuated, to feed a border panel forwardly over said cutting edge; C. a knife blade pivotally mounted at one end for movement back and forth across said cutting edge between ready and spent positions; D. power means operative, when actuated one way and the other, to move said knife from its ready position to its spent position to cut said panel and vice versa to return said knife to its ready position; E. control means for automatically actuating said power means; and F. yieldable means engaging the knife during its panel cutting movement and, through such engagement, pressing the cutting edge of the knife yieldably into cutting engagement with a panel on said fixed cutting edge, 1. said yieldable means includes a bar pivotally mounted at one end and yieldably urged at its opposite end into engagement with the knife.
Claim 3
Dependent Claim
78 words
The machine of claim 1 wherein: A. said pivotally mounted knife moves in one vertical plane between an upper ready and a lower spent position; B. said yieldable means tends to flex the knife in a direction at right angles to the cutting movement of the knife; and C. said power means is mounted on the machine for pivotal movement corresponding to and accommodating said pivotal movement of the knife and for pivotal movement at right angles thereto.
