PURPOSE: To provide a tenter which ensures uniformity of a traveling endless fabric and prevents from generation of tacks or folding by maintaining the velocity of the fabric rims of the traveling endless fabric so that it is equal to the velocity of an intermediate zone. ;CONSTITUTION: A tenter for an endless fabric, which is used for heat treatment as a partial process related to production of a fabric for a paper machine in particular, is constituted of several carriages 1 guiding the fabric rims by means of a carriage 2 for each carriage 1. Each carriage 1 comprises at least one spring 4 arranged between the carrier 2 and an abutment in the carriage 1 such that the velocity of each carriage 1 substantially corresponds to the speed of the fabric rim. It also includes a mechanism for registering and monitoring the tension force in the material based on which the velocity of the drive chain and the carrier 2 is adjusted to maintain a desired velocity for the fabric through the heat treatment zone.;COPYRIGHT: (C)1994,JPO
