Changing cloth beams in a weaving mill
First Claim
1. A method of changing cloth beams in a weaving mill comprising the steps oftransferring a full cloth beam from a weaving machine into a predetermined position in a transporter;
- moving a wind-on beam into the path of fabric between the weaving machine and full cloth beam to form a loop of fabric;
moving the wind-on beam with the loop of fabric about a fresh cloth beam in the transporter;
cutting the fabric between the fresh cloth beam and full cloth beam;
positioning a free cut end of the fabric against the fresh cloth beam;
rotating the fresh cloth beam to wind the fabric thereon over the free cut end of the fabric; and
transferring the fresh cloth beam with the fabric windings thereon to the weaving machine.

Abstract
A transporter is constructed to exchange an empty cloth beam for a full cloth beam of a weaving machine; the cloth being wound into the empty beam while the empty beams remains in the transporter. The transporter has a pair of gripper arm which are automatically acutated in order to transfer a full cloth beam from the weaving machine into the transporter. The gripper arms thereafter move a wind-on beam within the transporter into a position to effect a transfer of the cloth to a fresh cloth beam in the transporter. The gripper arms then move the fresh cloth beam into the weaving machine.

10. A transporter for a weaving mill comprising
first means for mounting a full cloth beam thereon; -
second means for mounting a fresh cloth beam in parallel relation to the full cloth beam; a wind-on beam mounted below said first means; a pair of movable gripper arms, said arms being movable from a first position engaging said wind-on beam to a second position positioning said wind-on beam between said first means and said second means to form a loop in a fabric extending from a weaving machine to the mounted full cloth beam, said arms being movable to a third position engaging the fresh cloth beam and to a fourth position positioning the fresh cloth beam in the weaving machine; and a cutter for cutting the loop of fabric between the mounted full cloth beam and the fresh cloth beam to form a free end of fabric for winding onto the fresh cloth beam. - View Dependent Claims (11, 12)
