A method for producing a profiled spine in a book having a first side defining a first plane, a second side defining a second plane and a spine. The method includes clamping the book using a first clamp element contacting the first side and the second clamp element contacting the second side and moving the first element with respect to the second element so as to skew the spine by moving at least one of the first side in the first plane and the second side in the second plane.

A system for controlling the consistency of a material pumped from a reservoir, by introducing an alterant into the material, which system includes a diaphragm-type pump for pumping the material from a reservoir, the pump being driven by a double-acting air cylinder motor controlled by a pilot-operated two-position, four-way air valve having reducing valves connected at its air input ports to create pressure differentials between the input air and the operating air in the cylinder during steady state-operation of the pump. The motor is mounted so as to be relatively movable substantially toward and away from the pump responsively to change in the pressure differentials in the cylinder due to changes in the consistency. A compression spring, forming part of the mounting, is disposed so that under steady state conditions of consistency of material being pumped, an equilibrium exists between the forces acting between the motor and the pump, and the force acting on the motor by the spring, and the motor and pump do not move relatively to one another. A change in the consistency of the material will disturb that equilibrium, causing the motor to move relatively to the pump, and such movement serves to operate a valve that controls the introduction of alterant into the material.
