The connecting means at this time may be a general bolt nut, and the bolt may be inserted into a bolt hole formed in the connecting surface and tightened so that the connecting surface is brought into close contact. However, one of the connecting holes on one of the connecting surfaces corresponds to the plurality of the connecting surfaces in the front-rear direction, and the relative position of the front and rear frames is adjusted by selecting the latter one. It shall be. The latter plurality of bolt holes may be replaced with long holes.
[0011]
The required space between the front frame and the rear frame accommodates the constituent members of the opening device depending on the number specifications of the eaves frame. However, the component member here is a guide roll device that guides the wire for driving the saddle frame, for example, in the case of a cam opening device driven by depolarization, and the guide roll device has a number corresponding to the number of specifications of the collar frame. A guide roll is mounted on a common support shaft in the front-rear direction. In addition, in the case of a positive drive cam opening device, the component members are a crank lever for driving a saddle frame, a connecting rod, etc., and these members are also arranged in the front-rear direction in pairs corresponding to the number of specifications of the saddle frame. Yes. Further, the constituent member may be a shedding lever of a crank opening device or the like. In addition, a required space shall be set so that the structural member of an opening apparatus and the flange of a warp beam may not mutually interfere mechanically.
[0012]
By connecting the upward and downward horizontal surfaces, the connection surface stably supports part or all of the weight on the side that forms the downward connection surface by the side that forms the upward connection surface of the front and rear frames. can do. In addition, the connection surface can be made simple by making the inward and outward vertical surfaces face each other, and the left and right positioning operations of the front frame and the rear frame can be substantially eliminated. Furthermore, a connection surface can implement | achieve both advantages collectively by making the combined surface of a horizontal surface and a vertical surface face.
[0013]
By connecting the left and right side plates via the cross beams, the front frame can be improved in rigidity and the assembly work can be further facilitated. The same applies to the rear frame.
[0014]
The required space formed between the front frame and the rear frame needs to be set so that the constituent members of the opening device are accommodated and the flange of the warp beam does not mechanically interfere with the constituent members. Therefore, the required space can be set more appropriately by making it depend on the flange diameter of the warp beam in addition to the specification of the number of reed frames.
