Abstract
A sawblade machine has its setting members disposed adjacent the sawblade in nonclamping engagement therewith and defining an angle of the setting surfaces in excess of the angle defined between the outer planes of the teeth in the starting position. The setting members are then rotated to the teeth and returned to the starting position whereupon the clamping heads are relieved and the blade advanced.
Claims18
A device for setting a row of teeth of a sawblade, said device comprising:
- a pair of clamping members disposed on opposite sides of a sawblade having a row of teeth to be set and engageable with said opposite sides below a tooth-foot line of said row;
- means operatively connected with said clamping members for pressing said clamping members against said sides of said sawblade;
- a pair of separate setting members on opposite sides of said row of teeth and having respective setting surfaces juxtaposed with teeth of the row, said setting members having fixed starting positions in which said setting members are simultaneously in clamping-free engagement with said sawblade from opposite sides, said setting surfaces defining a setting-tool angle between them in said starting position which is at least equal to a setting angle defined between outer tooth side planes upon setting of the teeth;
- and
- means for angularly displacing said setting members in opposite senses to press said setting surfaces against the teeth of said row and set said teeth so that outer tooth side flanks of set teeth lie in said outer tooth side planes at said setting angle.

A device for setting a row of teeth of a sawblade, said device comprising:
- a pair of clamping members disposed on opposite sides of a sawblade having a row of teeth to be set and engageable with said opposite sides below a tooth-foot line of said row;
- means operatively connected with said clamping members for dressing said clamping members against said sides of said sawblade;
- a pair of setting members on opposite sides of said row of teeth and having respective setting surfaces juxtaposed with teeth of the row, said setting members having starting position in which said setting members are in clamping-free engagement with said sawblade, said setting surfaces defining a setting-tool angle between them in said starting position which is at least equal to a setting angle defined between outer tooth side planes upon setting of the teeth;
- and
- means for displacing said setting members to press said setting surfaces against the teeth of said row and set said teeth so that outer tooth side flanks of set teeth lie in said outer tooth side planes at said setting angle, said means for displacing said setting members including means for enabling displacement of said setting members transverse to said sawblade only in the form of angular movement of said setting members, each of said setting members being provided with a circular guide along which said setting members are displaceable, each of said setting members engaging said row of teeth along a contact line in said rest position, said circular guides being centered on said contact lines.
