摘要:
A bag forming machine including folding means (10,11) for folding a web of fabric (66) to form two superimposed layers of fabric joined along one side by a fold, holding means (20,21) for holding the folded fabric along the side edge opposite the fold, severing means for severing the folded fabric from the web of fabric material, and sewing means (40,41) for seaming the folded fabric along the edge opposite said fold and along one end edge extending between the fold and said side edge.

A gripper (10) for an Axminster gripper loom comprises a gripper body (12) and a gripper jaw (14). The gripper body (12) and the gripper jaw (14) are formed to define mutually engageable connectors (24,40) to pivotally connect the gripper jaw (14) to the gripper body (12).
摘要:
An apparatus, for weaving leno fabric on a loom, including: a support having pivot means which enable the support to be pivotally mounted on the loom for reciprocal pivotal rotation about a pivot axis, the support carrying a plurality of ground thread blades arranged side by side in a row and spaced apart along the row to define inbetween neighbouring ground thread blades a guide space for a ground thread running along a predetermined pathway, a leno guide blade being located in each guide space to divide the guide space into first and second guide slots, each leno guide blade having at its terminal end a leno guide eye through which a leno thread is to be guided, adjacent ground thread blades projecting beyond the terminal end of the leno guide blade located therebetween to define a ground thread cross-over space, the ground thread and leno guide blades being arranged to extend from said pivotal axis as defined by the pivot means such that pivotal movement of the support in a first rotary direction causes the ground threads to move relatively along one of the first or second guide slots towards and into the cross-over spaces and thereby permit the ground threads to be moved laterally relative to the leno guide blades from one side to the other thereof; and such that pivotal movement of the support in a second rotary direction opposite to the said first rotary direction causes the ground threads to move relative to the ground thread blades out of the cross-over spaces and relatively along the other of the first or second guide slots away from the cross-over spaces.

A pile loop forming assembly for a loom, the assembly including loop forming assembly for a loom, the assembly including a reed (20) having a plurality of reed fingers (21) spaced apart to define reed spaces (24) inbetween adjacent pairs of said reed fingers (21), a plurality of loop forming lances (7), each lance (7) extending through a respective reed space (24) in order to divide the reed space into first and second longitudinal regions (50,51) and to divide the first longitudinal region into a first warp yarn accommodating space (52) and a second warp yarn accommodating space (53), held means for normally retaining a loop forming warp yarn (6,8,25) in said first longitudinal region (50) during shed formation, the held means being selectively operable to move the loop forming warp yarn (6,8,25) from said first longitudinal region (50) to the second longitudinal region (51) so as to move said yarn out of said first or second warp yarn accommodating space, deflection means operatively connected to each lance (7) for laterally deflecting the lance (7) toward one or other of the reed fingers (21) defining the reed space (24) through which the lance (7) passes, such that the lance (7) resides at first and second lateral positions respectively, the lance (7) when at said first lateral position co-operating with said one reed finger to deflect said loop forming yarn (6,8,25) into said first warp yarn accommodating space (52) when moving from said second longitudinal space (51) and into said first longitudinal space (50) and when at said second lateral position co-operating with said other reed finger to deflect said loop forming yarn (6,8,25) into said second warp yarn accommodating space (53).

摘要:
A yarn carrier (30) for presenting a selected yarn (16) to a pair of gripper jaws (26,28). The yarn carrier (30) includes a yarn guide passageway (14) defining a path along which the selected yarn (16) is longitudinally guided. The passageway (14) has a yarn inlet end, a yarn outlet end and adjacent to the yarn outlet end yarn guides (32) to constrain the tail of the yarn (Y T ) against lateral deflection in a longitudinal direction of the yarn carrier (30). The yarn guides (32) are depressible on contact with open gripper jaws (26,28) to enable the gripper jaws (26,28) to grip the yarn tail (Y T ).
摘要:
A reed assembly for leno weaving, the reed assembly including upper and lower reed frame members (22, 23) between which a plurality of dent fingers (25) extend, each pair of neighbouring dent fingers (25) being spaced apart to define a dent space (26) for a crossing-over warp yarn (5), a yarn guide finger (27) co-operating with each dent space (26) for guiding a crossed-over warp yarn (5) therethrough, each yarn guide finger (27) extending from one of the frame members (23) and having a terminal end spaced from the other frame member (22) so as to divide the co-operating dent space (26) into a pair of cross-over dent spaces (26a, 26b) extending between said terminal end and said one frame member (23) and being defined between facing sides of the guide finger (27) and the pair of neighbouring dent fingers (25) and a cross-over transfer region extending between said terminal end and said other frame member (22) and being located between opposed faces of the pair of neighbouring dent fingers.
