<p>The felt of the pile threads and of the subsequent series are attached to each other by a hardening agent. This is intermittently fed to the pile at its foot after the series of fibres has been pushed in the correct position in relation to the previous series employing a support forming a stationary plateau. The series of pile fibres is intermittently moved in the direction of an intermittently moving conveyor belt where the agent is hardened.</p> |
