Abstract
In a loom having mechanically driven weft thread insertion members, a weaving reed and a guide element for a weft thread gripper cooperate with one another, so that the guide element guidedly runs along the reed to provide an positive guidance for the gripper while it inserts a weft thread. To achieve this, each one of the reed teeth (6) has a profile recess (6D) therein between the upper and lower reed frame members (1A, 1B). The recesses are aligned with each other to form a guide channel across the width of the weaving reed (1). A protruding extension (13A) of the guide element (13) mounted on the gripper (12) is temporarily guidingly connected or engaged with the guide groove as the weft thread insertion members reach into and out of the loom shed.
Claims20
In a loom having a mechanically driven rapier weft thread insertion member for inserting a weft thread, an improved weaving reed comprising a first reed frame member, a second reed frame member, and a plurality of reed teeth that are arranged spaced apart and parallel to each other in a row and that are respectively connected between said first and second reed frame members, wherein said reed teeth respectively have profile recesses with at least one of said profile recesses provided in each one of said reed teeth between said first and second reed frame members, and wherein said recesses are adapted to guide the rapier weft thread insertion member across a weaving width of said reed.
A loom comprising a weaving reed, and a weft thread insertion member adapted to be alternately inserted into and retracted out of a loom shed formed in said loom, wherein:
- said weft thread insertion member comprises a carrier member, a weft thread gripper arranged at an end of said carrier member, and a guide element that contacts said weaving reed in a guidedly movable manner,
- said guide element includes a protruding extension that protrudes toward said weaving reed,
- said weaving reed comprises a first reed frame member, a second reed frame member, and a plurality of reed teeth extending between and respectively connected to said first and second reed frame members,
- said reed teeth respectively comprise beat-up edges adapted to beat-up a weft thread in said loom and back edges opposite said beat-up edges, and respectively have profile recesses in said beat-up edges,
- said profile recesses of said reed teeth substantially align with each other to form a guide channel extending along a weaving width of said weaving reed, and
- said protruding extension of said guide element has a profile shape adapted to reach into said profile recesses and at least temporarily engages said guide channel in a guidedly movable manner.
A guide element for guidingly interconnecting a weft thread insertion gripper and a weaving reed in a loom, said guide element comprising an abutment surface adapted to abut against a side wall of the gripper, an elastic mounting element adapted to connect said guide element to the gripper, a first gliding contact guide surface that is spaced apart from and extends at an acute angle relative to said abutment surface and that is adapted to make gliding contact with a beat-up edge of reed teeth of the reed, and a second gliding contact guide surface that extends from said first guide surface and forms a profile contour that runs into said abutment surface.
